Replacing a Roman Tub

A Roman tub is the one you have been stepping around for years: a drop-in soaking tub dropped into a built-up, tiled platform, with a widespread faucet — separate spout, two handles, often a little hand shower — mounted straight through the deck instead of on the wall. Builders installed thousands of them in Sacramento and Placer County master baths from the 1980s through the 2000s because the tiled platform read as luxury. The deck-mounted faucet spread is what makes it a true Roman tub, and it is also what makes replacing one a bit more involved than swapping a plain alcove tub.

The good news is that the platform hiding all that plumbing is exactly the space you get to reclaim. Whether you want to convert the whole thing into a large walk-in shower or set a modern freestanding tub where the deck used to be, removing a Roman tub is one of the more satisfying bathroom projects we do at Oakwood Remodeling Group. If you already know a shower is where you are headed, our tub-to-shower conversion service covers the full scope, and this guide walks through what makes the Roman-tub version distinct — starting with that deck faucet.

What Makes a Roman Tub Different

People use "Roman tub" and "garden tub" almost interchangeably, and the platform demolition is genuinely similar. The distinction that matters on the plumbing side is the deck-mounted faucet. On a Roman setup, the spout and handles come up through holes drilled in the tiled deck, fed by rough-in valve bodies mounted to the framing underneath — completely hidden until you open the platform. There is no wall faucet to work with. That changes the removal in two ways: those deck penetrations and hidden valves have to be dealt with, and the layout naturally opens the door to a freestanding tub with its own floor- or rim-mounted filler.

If your tub has a wall-mounted faucet and a big tiled surround but no deck spread, you are closer to a standard garden tub, and our garden-tub-to-shower conversion guide covers the shared platform work in more depth. Everything below focuses on the deck-mount specifics and the freestanding-tub option that Roman tubs invite.

Why Homeowners Replace Them

Roman tubs look substantial and get used rarely. Climbing over the deck is awkward, a standard water heater struggles to fill the tub before it cools, and Sacramento's hard water leaves mineral rings on the tub and etches the deck tile and grout. Two decades on, most families treat the tub as a plant-and-towel shelf while showering in a cramped stall nearby. The tiled platform, meanwhile, occupies 15 to 30 square feet of prime master-bath floor. Replacing the Roman tub does not remove a feature you love — it removes a daily annoyance and hands back the room.

There are three directions worth weighing:

• Convert to a walk-in shower — remove the tub and platform and build one large walk-in across the reclaimed area, sometimes absorbing an adjacent small stall. The most common request and the best value.
• Swap in a freestanding tub — cap the deck-mount plumbing, tear out the platform, and set a modern freestanding soaker on the open floor with a floor-mount or rim filler. You keep a real soaking tub but lose the dated deck.
• Do both — in larger El Dorado Hills and Granite Bay masters, build a generous walk-in shower and set a freestanding tub in the remaining space for a true spa layout.

You can compare every path on our bathtub replacement guides.

Dealing With the Deck-Mounted Faucet and Platform

This is the part unique to Roman tubs, so it is worth understanding before demo day. The deck faucet is fed by valve bodies bolted to the platform framing below the tub deck, with supply lines running up to the drilled deck holes. When we open the platform, we expose those valves and the tub drain, then handle them based on your plan. Converting to a shower means capping the old deck supplies and running fresh water to a properly heighted wall valve, then relocating the drain to the new pan center. Going freestanding means capping or repurposing those supplies and running a new floor-mount filler line to wherever the tub will sit.

The tiled deck, the framed platform under it, any step-up, and the tiled backsplash all come out down to subfloor or slab. Underneath you typically find dimensional lumber, sometimes a mortar bed, and the drop-in tub resting in a cutout. We haul it all off and rebuild flat, code-compliant framing for the shower curb, curbless slope, or level tub base. On slab-on-grade homes common in Lincoln, Roseville and newer Rocklin subdivisions, any drain move means cutting and re-pouring concrete — the single biggest cost swing in the whole project.

Line-Item Cost Breakdown

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

• $1,200 – $3,000 — Demolition and disposal of the Roman tub, tiled deck, platform framing and backsplash, plus haul-off. Over-built platforms and stone decks push this higher.
• $1,500 – $4,500 — Plumbing: capping the deck-mount valves and supplies, plus either a new wall shower valve and drain relocation, or a new floor-mount tub filler line. Slab drain relocation sits at the top of the range.
• $900 – $2,200 — Framing and blocking for new shower walls, curb or curbless slope, or a level, reinforced base for a heavy freestanding tub.
• $1,500 – $3,500 — Waterproofing and shower pan (shower conversions only): membrane or foam system, sloped base, code-compliant to pass inspection.
• $1,200 – $6,000 — The new fixture: a quality freestanding soaking tub, or the shower surface materials if you skip the tub. Insulated acrylic tubs and designer fillers land higher.
• $3,500 – $12,000 — Shower wall surfaces (conversion path): large-format porcelain, solid surface, or premium panels; custom tile with 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 (shower path).
• $800 – $2,500 — Electrical, patch, paint and finish carpentry where the platform met the walls and floor.

A straight walk-in shower conversion commonly lands around $12,000 to $22,000. A clean freestanding-tub swap typically runs $6,000 to $14,000. A dual layout with both a shower and a freestanding tub can reach the $25,000 to $45,000 range. Placer County projects often run slightly higher than comparable Sacramento County ones, mostly due to labor demand and slab work in newer subdivisions.

The Process, Step by Step

• Design and measurement — we confirm the layout, the fixture you want, drain and filler locations, and finishes, then finalize the plan and pull the permit.
• Demolition — the Roman tub, tiled deck, platform framing and backsplash come out down to subfloor or slab, exposing the deck-mount valves and drain, and the debris is hauled off.
• Plumbing — a licensed plumber caps the old deck-mount supplies and either sets a wall shower valve and relocates the drain, or runs a new floor-mount filler for a freestanding tub; slab homes get the concrete cut and re-poured around any new drain.
• Framing and blocking — new walls, curb or curbless slope, bench and niche framing for a shower, or a level, reinforced base for a heavy soaking tub.
• Waterproofing and pan — for shower conversions, membrane, pan and inspection. This stage determines whether the shower lasts, so it is not rushed.
• Surfaces and fixture set — tile or panels go up, or the freestanding tub is set and connected; niches and benches are finished.
• Glass, trim and finish — glass is templated and installed on a shower, trim and heads or the tub filler 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 space with you.

What Drives the Price Up or Down

Two Roman-tub projects on the same street can price very differently. The big levers:

• Shower vs. freestanding tub — a shower adds a waterproofed pan and glass; a freestanding tub skips those but buys a fixture and a filler. Doing both roughly doubles the plumbing and material budget.
• How far the drain moves — reusing a nearby drain is cheap; moving it across a slab is the most expensive plumbing variable in the job.
• Deck-mount cleanup — capping and removing the hidden valve bodies is routine, but corroded or awkwardly buried rough-ins can add time.
• Custom tile vs. panels — a detailed porcelain shower with bench and niches costs far more in labor than large-format panels, though both can look excellent.
• Fixture and filler grade — a basic acrylic soaker with a simple filler is a fraction of an insulated designer tub with a floor-mount thermostatic filler.
• Slab vs. raised foundation — raised-floor Sacramento ranch homes 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 Roman tubs and their deck tile look tired is the same reason your replacement needs the right materials: local water is hard and 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 poorly sealed grout. For a shower conversion, porcelain and solid-surface walls shrug off buildup far better than marble or travertine, and low-iron glass with a factory hydrophobic coating squeegees clean instead of spotting. For a freestanding tub, a smooth acrylic or solid-surface shell wipes down far more easily than the old textured deck tile ever did. A whole-house softener protects the new fixture, the glass and the water heater at once and is worth discussing if you have been fighting orange rings for years.

Getting an Accurate Estimate

No one can price a Roman-tub replacement honestly without seeing the platform, the deck-mount valves 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.
