Replacing a Garden Tub With a Shower

Walk into almost any master bathroom built in the Sacramento and Placer County suburbs between the mid-1990s and the late 2000s and you will find the same thing: a large, deck-mounted garden tub tucked into a tiled platform in the corner, and a cramped 32-inch shower stall squeezed in beside it. It was the builder's idea of luxury at the time. Two decades later, the honest truth is that most families fill that tub once or twice a year — if that — and use it the rest of the time as a shelf for towels, plants and dust. Meanwhile they fight for elbow room in a shower barely wide enough to turn around in.

A garden-tub-to-shower conversion fixes exactly that. We remove the oversized tub and its platform, reclaim the footprint, and build a genuinely large, modern walk-in shower in its place. It is one of our favorite projects at Oakwood Remodeling Group because the payoff is so lopsided — moderate scope, dramatic daily improvement. If you already know a full walk-in is where you are headed, our tub-to-shower conversion service covers the whole process, and this guide walks through what makes the garden-tub version distinct.

The Garden Tub Problem

A garden tub is a large, freestanding-style soaking tub set into a built-up deck or platform. In Placer County tract homes — think the master baths of Roseville, Rocklin, Lincoln and parts of Granite Bay — that platform is typically framed out of lumber, topped with tile or cultured marble, and often includes a step-up, a tiled backsplash and a deck-mounted faucet. It looks substantial, and it is: the whole assembly commonly occupies 15 to 25 square feet of prime floor space.

The issue is that it does not earn that space. Garden tubs are awkward to climb into, slow to fill with a standard 40-gallon water heater, and shallow enough that a real soak means constantly topping off cooling water. Sacramento's hard water leaves mineral rings that never quite scrub out. For most households the tub becomes storage, and the family showers in a tiny stall that should never have been that small in a master suite. Converting the tub does not remove a beloved feature — it removes a daily annoyance and gives you back the room.

When the Conversion Makes Sense

This is the right move when the garden tub is unused, when the existing shower is too small, and when the home has at least one other bathtub somewhere for resale and for the rare bath. Nearly every 1990s-and-newer master bath in our service area checks all three boxes. It is an especially popular request in Roseville, Rocklin and Granite Bay, where the housing stock is full of these oversized-tub layouts and buyers openly prefer a big shower.

There are two main directions to take it:

• Full shower conversion — remove the tub and platform and build one large walk-in shower across the reclaimed area, sometimes absorbing the old small stall too. This is the most common and the best value.
• Shower plus freestanding tub — if the room is large (common in El Dorado Hills and Granite Bay masters), remove the dated deck tub, build a generous walk-in shower, and set a sleek freestanding soaking tub in the remaining space. You keep a tub, lose the platform, and get a true spa layout.

If you are still weighing a straight one-for-one swap instead, the difference between this project and replacing a standard alcove bathtub with a walk-in shower mostly comes down to that heavy platform demolition and the amount of space you get back. You can compare the full set of options on our bathtub replacement guides.

Layout Ideas for the Reclaimed Space

The oversized single shower

The most requested result: a 4-to-6-foot-wide walk-in with a built-in bench, two recessed niches, a rainfall head plus a handheld on a slide bar, and a frameless glass enclosure. Where the old tub and the tiny stall sat side by side, we combine both footprints into one impressive shower.

The curbless spa shower

Because we are already opening the floor to relocate the drain, a curbless, linear-drain entry is very achievable — particularly on the slab-on-grade homes common around Lincoln and Roseville. It is the cleanest modern look and a smart aging-in-place choice for Granite Bay and Auburn homeowners planning to stay put.

Shower and freestanding tub side by side

The premium option: a large walk-in shower and a separate freestanding soaker sharing the reclaimed wall, often under a window. It reads as a custom master suite and is the layout most likely to wow a future buyer.

Line-Item Cost Breakdown

Every bathroom is different, but here is a realistic 2026 breakdown for a garden-tub conversion in the Sacramento–Placer market. These are planning ranges, not a quote — your actual numbers depend on layout, finishes and how far plumbing has to move.

• $1,200 – $2,800 — Demolition and disposal of the garden tub, deck, platform framing and old shower stall, plus haul-off. Over-built platforms and tile decks push this higher.
• $1,800 – $4,500 — Plumbing relocation: new shower valve, drain move to the pan location, capping old tub supplies. Slab-on-grade drain relocation (cut and patch concrete) sits at the top of this range.
• $900 – $2,200 — Framing and blocking for the new shower walls, curb or curbless slope, bench and niches.
• $1,500 – $3,500 — Waterproofing and shower pan: proper membrane or foam system, sloped mortar bed or pre-formed base, code-compliant to pass inspection.
• $3,500 – $12,000 — Wall surfaces: large-format porcelain tile, solid surface, or high-end panels. Custom tile with a bench and niches lands in the upper half.
• $1,400 – $4,500 — Frameless or semi-frameless glass enclosure with low-iron, coated glass for hard-water resistance.
• $600 – $2,500 — Fixtures and finishes: shower valve trim, rainfall and handheld heads, hardware, glass door pull.
• $800 – $2,500 — Electrical, patch, paint and finish carpentry where the platform met walls and floor.

A straightforward full shower conversion in this market commonly lands around $12,000 to $22,000. Add a freestanding tub and premium finishes and you can move into the $25,000 to $45,000 range for a true dual-fixture master. Placer County projects often run slightly higher than comparable Sacramento County ones, largely due to labor demand and slab work in newer subdivisions.

The Conversion Process, Step by Step

• Design and measurement — we confirm the layout, drain location, finishes and whether you want curbless or a second tub, then finalize the plan and permit.
• Demolition — the garden tub, deck, platform framing and old stall come out down to subfloor or slab, and the debris is hauled off.
• Plumbing relocation — a licensed plumber moves the drain to the new pan location, sets the shower valve at proper height, and caps old lines; slab homes get the concrete cut and re-poured around the new drain.
• Framing and blocking — new walls, curb or curbless slope, bench and niche framing, and blocking for grab bars or glass.
• Waterproofing and pan — membrane, pan and inspection. This is the stage that determines whether the shower lasts, so it is not rushed.
• Tile or panel installation — walls, floor, niches and bench are finished in your chosen surface.
• Glass, fixtures and finish — glass is templated and installed, trim and heads go on, and we patch, paint and detail where the old platform used to be.
• Final inspection and walkthrough — the city or county signs off and we review the finished shower with you.

What Drives the Price Up or Down

Two projects on the same street can price very differently. The biggest levers:

• How far the drain moves — a short relocation is cheap; moving the drain across a slab is the single most expensive plumbing variable.
• Custom tile vs. panels — a detailed porcelain build with bench and niches costs far more in labor than large-format panels, though both can look excellent.
• Curbless entry — beautiful and accessible, but the extra slope and waterproofing work adds cost.
• Adding a freestanding tub — a second fixture means more plumbing, more space planning and a bigger material budget.
• Glass spec — frameless, low-iron, coated glass costs more than a semi-frameless panel but stands up far better to hard water.
• Slab vs. raised foundation — raised-floor homes (older Sacramento ranch stock) make drain moves easier than the slab foundations under most newer Placer County subdivisions.

Choosing Finishes That Survive Sacramento Hard Water

The reason so many garden tubs look tired is the same reason your next shower needs the right materials: local water is hard, and it is unforgiving of the wrong surfaces. Sacramento and Placer County tap water leaves mineral deposits that etch natural stone, haze cheap glass, and build up in the grout lines of a poorly sealed tile job. When we plan a conversion, finish selection is not an afterthought — it is what keeps the new shower looking new five and ten years out.

A few choices matter most. Porcelain and solid-surface walls shrug off mineral buildup far better than marble or travertine, which need frequent sealing and still spot. For glass, low-iron panels with a factory-applied hydrophobic coating resist water spotting and clean up with a quick squeegee instead of a scrub. Large-format tile or panels mean fewer grout joints, which means fewer places for hard water and soap scum to collect. And if you have ever fought orange rings in the old garden tub, a whole-house softener is worth discussing — it protects the new shower, your fixtures and the water heater at once. None of this is exotic; it is just the difference between a shower built for this region and one built to look good only on install day.

Getting an Accurate Estimate

No one can price a garden-tub conversion honestly without seeing the platform, the drain and the room. The ranges above will get you a realistic budget, but the number that matters comes from an in-home look at how your tub is built and how far the plumbing has to travel. Oakwood Remodeling Group is a bathroom-and-shower-only, licensed (#1125321), 5.0-star-rated remodeler based in Rocklin, and this is one of the conversions we do most often across Roseville, Rocklin, Granite Bay and the surrounding communities. Our work is backed by a 3-year workmanship and 10-year structural warranty.
