Tub to Shower Conversion: Cost, Timeline and What to Expect

If the bathtub in your home is used as a shower every day and as a tub almost never, you are stepping over a high wall for no reason. A tub to shower conversion replaces that tub with a dedicated shower in the same footprint, which is why it is one of the most requested bathroom changes among Houston homeowners.

Because the new shower usually sits exactly where the tub was, the project is more contained than a full bathroom remodel. It still involves plumbing, waterproofing and tile, though, so it helps to understand what affects the price, how the work is sequenced and what you will live with while it happens.

Is a Tub to Shower Conversion Right for Your Home?

A conversion makes sense when the tub is rarely used for bathing, when stepping over the tub wall is becoming difficult or unsafe, or when you simply want a roomier, easier-to-clean place to shower.

The main reason to pause is if it is the only bathtub in the house. Families with young children often want one, and some future buyers will look for one. Many homeowners keep a tub in a hall bathroom and convert the one in the primary bathroom. There is no rule here, only a decision that should be made on purpose.

What Drives the Cost

We do not publish prices, because an honest figure depends on your bathroom. These are the factors that determine where a conversion lands.

• Shower base: a prefabricated pan sized to the old tub opening costs less than a custom tiled base built and waterproofed on site.

• Wall surface: solid wall panels install faster than tile. With tile, the material chosen and the complexity of the pattern both affect labor.

• Drain work: a shower drain is often a different size and in a different position than a tub drain. In a slab-foundation home, adjusting it can mean opening a section of concrete.

• Valve and fixtures: the old tub valve is normally replaced. Adding a handheld sprayer or a second showerhead adds plumbing.

• Glass: a curtain rod, a framed sliding door and a frameless enclosure sit at very different price points.

• Curb height: a low curb is simpler than a curbless entry, which requires the floor to be recessed or sloped.

• Hidden conditions: water damage, mold or deteriorated framing behind old tub walls must be repaired before anything new goes in.

• Added features: a bench, niches and grab-bar blocking each add some labor and material.

Permits may apply because plumbing is being altered. Requirements vary by city and HOA, so your contractor should confirm what is needed and include it in the quote.

How the Timeline Unfolds

A conversion is among the shorter bathroom projects, but the exact duration depends on the choices above, particularly tile versus panels and stock versus custom glass. Rather than promise a number, here is the sequence and where time tends to go.

• Planning and ordering: selections are finalized and materials ordered before demolition, so the bathroom is not torn apart while waiting on deliveries.

• Demolition: the tub and surrounding wall surface are removed and the framing, subfloor or slab and plumbing are inspected.

• Rough plumbing: the drain is adjusted and the new valve installed, followed by any required inspection.

• Base and waterproofing: the pan is set or built, and the walls are prepared and waterproofed. Some materials need curing time that cannot be rushed.

• Tile or panels: tile is set, then grouted, with drying time between steps. Panels move faster.

• Fixtures and glass: trim and showerheads go on. Custom glass is typically measured only after the tile is finished and then fabricated, so it is often the last piece to arrive.

The two most common causes of delay are repairs discovered after demolition and waiting for custom glass.

What to Expect During the Work

That bathroom will be out of service for the duration, so plan to use another one. Demolition is the loudest and dustiest stage. A careful crew will protect floors along the path to the bathroom and contain dust as much as possible.

Expect a conversation after demolition. That is when the contractor can finally see what is behind the walls. In Houston's humid climate, and in older homes especially, it is not unusual to find moisture damage around an old tub. Dealing with it properly at this point is far better than sealing it behind new tile.

You may also need to make decisions about the surrounding room. Removing a tub can expose flooring and wall areas that the tub used to cover, so some patching or new floor tile next to the shower is often part of the job. Homeowners sometimes use the opportunity to update the vanity or lighting at the same time. See our bathroom remodeling services if you are considering more than the conversion alone.

Details Worth Deciding Up Front

• Where the controls go. Placing the valve near the entry lets you turn on the water without standing under it.

• Whether to add blocking in the walls for grab bars, even if you do not install them now.

• Bench or no bench, and built-in niches for storage.

• Which way a door will swing, or whether a fixed panel suits the room better.

• A slip-resistant floor surface for the shower base.

Frequently Asked Questions

Will the new shower fit where my tub is now?

Almost always. A standard tub alcove is a good size for a comfortable shower, and many shower bases are made to fit that opening. This is what keeps most conversions from requiring walls to be moved.

Does the drain have to be changed?

Often, yes. Showers and tubs commonly use different drain sizes and positions, so the plumber usually modifies the drain line. How involved that is depends on your home's construction, and your contractor should confirm it during the site visit.

Will converting my only tub hurt resale?

It depends on the home and the likely buyer. Some buyers, especially families with small children, prefer at least one bathtub, while others value a well-built shower more. If resale matters to you, keeping one tub somewhere in the house is the cautious approach.

Can I use the shower as soon as the tile is finished?

Not immediately. Grout, sealants and the caulk around glass need time to cure before they get wet. Your contractor will tell you when the shower is ready for use.
