El Dorado Hills Tub-to-Shower Conversion: Why EDH Homeowners Are Making the Switch

Why El Dorado Hills Homeowners Are Removing Bathtubs

If you live in El Dorado Hills, there is a good chance your master bathroom features a large garden tub or soaking tub that rarely gets used. Homes built across Serrano, Promontory, Blackstone, and Highland Hills from the mid-1990s through the 2010s almost universally included oversized master bath tubs as the centerpiece of the bathroom design. Builders treated the garden tub as a non-negotiable luxury feature, positioning it beneath a picture window or against an accent wall, often alongside a separate — and noticeably smaller — shower stall.

Two decades later, El Dorado Hills homeowners have realized what the data confirms: fewer than 15 percent of homeowners use their master bath soaking tub on a regular basis. That oversized tub occupies 25 to 35 square feet of premium bathroom floor space, requires regular cleaning even when unused, and forces the daily-use shower into a cramped 36-by-36-inch or 36-by-48-inch fiberglass insert that feels entirely inadequate for a home valued between $800,000 and $1.2 million.

The disconnect between how the bathroom was designed and how it is actually used has made the tub-to-shower conversion the single most requested bathroom renovation in El Dorado Hills. Homeowners are not abandoning bathtubs on a whim. They are making a calculated decision to invest in the fixture they use twice daily — the shower — instead of maintaining a feature that sits idle 95 percent of the time.

This shift is especially pronounced in EDH because the community's homes are large enough to maintain a bathtub in a secondary bathroom. Most Serrano and Promontory homes have three to five bathrooms, giving homeowners the flexibility to convert the master tub without eliminating tubs from the home entirely. It is the best of both worlds: a luxury walk-in shower where you shower daily, and a bathtub in the guest or kids' bathroom where it actually gets used.

The Tub-to-Shower Conversion Process Step by Step

A tub-to-shower conversion is a well-established renovation that an experienced bathroom specialist completes routinely. Understanding the process helps you plan around the construction timeline and set realistic expectations. Here is exactly what happens during a tub-to-shower conversion in a typical El Dorado Hills home.

Step 1: Pre-Construction Planning (1-2 Weeks)

Before any demolition begins, your contractor conducts a detailed site assessment. This includes measuring the existing tub alcove or deck footprint, identifying the location of plumbing supply lines and drains, checking the subfloor condition from accessible points, and documenting the wall framing configuration. Material selections are finalized, including tile, glass enclosure type, fixtures, and drain style. Your contractor submits permit applications to El Dorado County and orders all materials so everything is on-site before the first day of construction.

Step 2: Demolition and Inspection (Days 1-2)

The existing garden tub, surround, and any surrounding deck or tile work are carefully removed. This phase reveals the true condition of the subfloor beneath the tub — a critical inspection point. In El Dorado Hills homes built during the 1990s and 2000s, it is common to find minor moisture damage or deteriorated OSB subfloor material beneath older tubs, especially if the original caulking failed at any point over the past 20 to 30 years. Any compromised subfloor is repaired or replaced before proceeding.

Step 3: Plumbing Modification (Days 2-3)

Bathtub drains and shower drains sit in different positions with different trap configurations. The existing tub drain must be relocated to align with the new shower layout. The shower valve position may need adjustment — garden tubs often have the valve mounted lower on the wall, while showers require the valve at approximately 48 inches above the finished floor. Supply lines are verified and upgraded if the original copper or CPVC is showing wear. This plumbing phase typically adds $1,500 to $3,000 to the overall project cost.

Step 4: Shower Pan and Waterproofing (Days 3-5)

The shower pan is constructed with proper slope — a minimum of one-quarter inch per foot toward the drain — using either a mortar bed or a pre-formed pan system. The entire shower area then receives a continuous waterproofing membrane. We use systems like Schluter Kerdi or Laticrete Hydro Ban that create a bonded, monolithic waterproof layer across the floor, walls, bench, niches, and all transitions. This is the single most critical phase of the entire conversion. Inadequate waterproofing leads to leaks, mold, and structural damage that can cost tens of thousands of dollars to remediate.

Step 5: Tile Installation (Days 5-10)

Tile is installed on the shower floor, walls, bench, and niches. Large-format tiles — increasingly popular in El Dorado Hills — require careful attention to substrate flatness and full mortar coverage on the back of each tile. The grout is applied, cleaned, and sealed. Tile work is where craftsmanship becomes visible. Perfectly aligned grout lines, clean mitered edges at corners, and symmetrical layouts around niches and fixtures distinguish professional work from amateur efforts.

Step 6: Glass, Fixtures, and Finishing (Days 10-14)

The frameless glass panel or full enclosure is measured, fabricated (custom glass requires 2-3 weeks of lead time after measurement), and installed. Shower fixtures including the valve trim, shower head, handheld spray, and any body sprays are installed and tested. Final silicone caulking is applied at all glass-to-tile and tile-to-fixture transitions. The shower is tested with a full water flow to verify drainage, waterproofing integrity, and proper fixture operation.

The conversion process transforms a dated garden tub alcove into a spacious, spa-quality walk-in shower in 2-3 weeks of active construction

Walk-In Shower Options After Conversion

The footprint left by a garden tub removal creates excellent opportunities for a spacious walk-in shower. The typical EDH garden tub alcove measures 60 by 42 inches or larger, which translates to a generous shower space that far exceeds the cramped original stall. Here are the most popular configurations El Dorado Hills homeowners choose.

Curbless Walk-In with Fixed Glass Panel

The premium option and by far the most requested in EDH luxury homes. A curbless (zero-threshold) entry with a single large fixed glass panel creates an open, seamless transition from the bathroom floor into the shower. This design requires precise floor engineering to slope correctly toward a linear drain while maintaining water containment. The visual impact is dramatic — the shower appears to float within the bathroom rather than being a boxed-in enclosure.

Low-Curb Shower with Frameless Enclosure

A low curb (typically 1 to 2 inches) with a full frameless glass enclosure provides maximum water containment with a near-seamless entry. This option works well in EDH homes where the existing floor structure makes a fully curbless design impractical without extensive subfloor modification. The frameless glass keeps the open, airy feel while the low curb provides reliable water management.

Tub-to-Shower with Built-In Bench and Niches

Adding a built-in bench seat and two or three recessed niches transforms the shower from a utilitarian space into a true spa retreat. The bench provides seating for shaving, relaxation, or accessibility needs. Niches eliminate the need for hanging caddies and keep products organized at arm's reach. In El Dorado Hills master bathrooms, this combination is nearly universal — homeowners who invest in a conversion expect these comfort features as standard.

El Dorado Hills Tub-to-Shower Conversion Cost Breakdown

The cost of a tub-to-shower conversion in El Dorado Hills depends on the scope of work, material selections, and the complexity of the existing plumbing and structural conditions. Here is a realistic breakdown based on current 2026 pricing for the EDH market.

Most El Dorado Hills homeowners invest in the luxury tier ($13,000 to $20,000). This price point delivers the material quality, craftsmanship, and design features that match the caliber of homes in Serrano, Promontory, and Blackstone. Going below the standard tier often means compromising on materials or workmanship in ways that are visually obvious in a high-end home.

These costs include all labor, materials, permits, and disposal. They do not include additional work outside the shower footprint, such as replacing the bathroom flooring, updating the vanity, or moving walls. If you are considering a broader master bathroom remodel that includes the tub-to-shower conversion, expect total project costs of $25,000 to $65,000 or more depending on the full scope.

Which Bathrooms to Convert: Master vs. Guest Strategy

El Dorado Hills homes typically have three to five bathrooms, which creates a strategic decision: which tubs do you convert, which do you keep, and in what order? The answer depends on your home's layout, your family's needs, and your long-term plans.

The Master Bathroom: Always Convert First

The master bathroom is where you start. You and your partner use this shower every single day, often twice. The garden tub sitting in the corner is the largest underutilized feature in your home. Converting it to a walk-in shower delivers immediate, daily quality-of-life improvement that you experience from the first morning after completion. The master bath conversion also provides the highest return on investment because it is the bathroom that buyers evaluate most critically when you eventually sell.

The Guest or Hall Bathroom: Keep the Tub

Maintain at least one bathtub in the home, ideally in the guest bathroom or hall bathroom that children use. This satisfies the one-tub rule for resale value and provides a functional tub for bathing young children, soaking after exercise, or accommodating guests who prefer baths. In most EDH floor plans, the hall bathroom between secondary bedrooms is the logical place to retain a tub.

Secondary Master or In-Law Suite: Consider Converting

Many Serrano and Promontory homes include a secondary master suite or in-law suite on the ground floor. If this bathroom has a tub that is rarely used — and if the home retains a tub elsewhere — converting it to a walk-in shower with aging-in-place features (curbless entry, grab bars, bench seat) creates a bathroom that serves aging parents now and adds long-term accessibility value to the home.

EDH Resale Impact of Removing a Tub

The question every El Dorado Hills homeowner asks before committing to a tub-to-shower conversion: will removing a bathtub hurt my home's value? The answer, supported by both national data and local market experience, is nuanced but overwhelmingly positive.

According to the National Association of Realtors 2025 Remodeling Impact Report, bathroom renovations that include a walk-in shower replacement recover 71 to 78 percent of their cost at resale, with higher recovery rates in affluent markets. El Dorado Hills qualifies as an affluent market by any measure, with median home values ranging from $800,000 to well over $1.2 million depending on the neighborhood.

The critical factor is maintaining at least one bathtub in the home. Homes with zero bathtubs can experience buyer resistance, particularly from families with young children. But homes that convert the master tub to a walk-in shower while retaining a guest or secondary bathroom tub consistently perform well in the EDH real estate market. Local agents report that luxury walk-in showers in the master suite are among the most-requested features by El Dorado Hills buyers.

In neighborhoods like Serrano and Promontory where homes regularly sell above $1 million, an updated master bathroom with a stunning walk-in shower can be the differentiator that moves a listing from "nice" to "must have" in a buyer's mind. The garden tub with its dated cultured marble surround signals a bathroom that has not been updated, while a modern walk-in shower signals a home that has been thoughtfully maintained and improved.

Neighborhood-Specific Considerations in El Dorado Hills

El Dorado Hills is not a monolithic community. Each neighborhood has distinct home vintages, floor plans, and market expectations that influence the tub-to-shower conversion approach.

Serrano

Serrano homes built from the late 1990s through the 2010s feature spacious master bathrooms with large garden tubs, separate shower stalls, and dual vanities. The tub footprints are generous — often 60 by 42 inches or larger — providing excellent conversion opportunities. The community's luxury market position means homeowners typically invest in the luxury or ultra-luxury tier to maintain consistency with the neighborhood standard.

Promontory

Promontory's semi-custom and custom homes from the 2000s often have even larger master bathrooms with oversized soaking tubs. Some feature platform tubs with surrounding tile decks that create an exceptionally large conversion footprint. These projects can accommodate walk-in showers with dual shower heads, expansive bench seating, and curbless designs that rival high-end spa facilities.

Blackstone and Highland Hills

These neighborhoods feature newer construction — many homes built in the 2010s and 2020s — with more modern floor plans. Some newer homes already include walk-in showers in the master bath, but many still have the builder-grade garden tub configuration. Conversions in these homes benefit from newer plumbing infrastructure and often have fewer subfloor issues to address.

Crown Valley, Woodridge, and Stonegate

These established neighborhoods include a mix of home vintages and price points. Conversions here often fall in the standard to luxury tier, with homeowners focused on practical improvements that enhance daily life and position the home well for eventual resale. The standard tier ($7,500 to $13,000) delivers excellent value in these neighborhoods.

El Dorado County Permit Requirements

El Dorado Hills falls under El Dorado County jurisdiction for building permits. Unlike some neighboring communities in Placer County, El Dorado County requires permits for tub-to-shower conversions because the project involves plumbing modifications that affect the drainage system.

The permits required for a typical EDH tub-to-shower conversion include:

• Building permit: Required for the structural and waterproofing modifications involved in converting the tub space to a shower. The building department reviews plans to ensure compliance with the California Residential Code, including shower size minimums, waterproofing requirements, and ventilation standards.
• Plumbing permit: Required for all drain relocation, valve repositioning, and supply line modifications. A licensed plumber or a contractor with appropriate license classification must perform this work.
• Electrical permit (if applicable): Required if the project includes new lighting, exhaust fan replacement or relocation, heated floors, or any other electrical modifications within the bathroom.

El Dorado County permit fees for a bathroom conversion project typically range from $300 to $800 depending on the scope. Processing time is generally 1 to 2 weeks for plan review. Oakwood Remodeling Group handles all permit applications, plan submissions, and inspections as a standard part of every El Dorado Hills conversion project — you do not need to visit the county offices or manage the permitting process yourself.

Waterproofing: The Hidden Make-or-Break

Waterproofing is the most critical element of any tub-to-shower conversion, and it is entirely invisible once the tile goes up. This is where the difference between a bathroom-only specialist and a general contractor or handyman becomes most consequential.

A properly waterproofed shower uses a continuous, bonded membrane system that covers every surface the water can reach: the shower floor, all walls to at least 72 inches above the floor (or ceiling height if ceiling-mounted fixtures are present), the bench top and all bench surfaces, inside all niches, and every corner and transition point. The membrane must be installed in a specific sequence with proper overlap, with all seams sealed using manufacturer-approved band and sealant.

A failed waterproofing system does not announce itself immediately. Water penetrates through tile and grout, reaches the unprotected wall or floor structure behind the membrane failure, and slowly causes rot, mold growth, and structural deterioration. By the time visible signs appear — staining on the ceiling below, musty odors, soft drywall — the damage behind the walls can be extensive. We have seen remediation costs from failed waterproofing reach $15,000 to $30,000 or more in El Dorado Hills homes.

This is not a scare tactic. It is a practical reason to hire a shower remodeling specialist who installs waterproofing systems daily rather than occasionally. At Oakwood Remodeling Group, waterproofing is not a step in the process — it is the foundation of the entire project, and we document every stage with photos for your records.

Project Timeline and What to Expect

Here is a realistic timeline for a tub-to-shower conversion in El Dorado Hills from initial contact to finished shower:

• Week 1-2: Consultation and design. In-home measurement, design consultation, material selection, and detailed estimate. You choose tile, glass, fixtures, and layout.
• Week 2-3: Permits and procurement. Permit applications submitted to El Dorado County. Materials ordered including custom glass fabrication (2-3 week lead time for frameless glass).
• Week 4-6: Active construction. Two to three weeks of on-site construction including demolition, plumbing, waterproofing, tile, glass installation, and fixtures.
• Week 6-7: Final inspection and completion. El Dorado County final inspection, punch list review, and project handoff. Your new walk-in shower is ready to use.

Total timeline from first contact to finished shower is typically 6 to 8 weeks. The master bathroom is out of service during the 2-3 week active construction phase. We recommend having an alternative bathroom available during this period, which is straightforward in most EDH homes with three or more bathrooms.
