What affects the cost of a tub-to-shower conversion?

Wall material

This is one of the biggest choices. Seamless acrylic wall panels go up faster than tile and need no regrouting later, which usually keeps both the install cost and the long-term upkeep down. Tile and natural stone take more labor and more time.

Shower size and base

A standard-size base is the most economical. Custom sizes, oversized showers and curbless entries cost more because they involve more building work. If you are weighing options, our guides to tub-to-shower conversion and walk-in shower installation explain what is involved.

Glass door or enclosure

Framed sliding doors, frameless glass and fixed panels are priced differently. A sliding glass door is a popular, practical choice for most conversions.

Plumbing changes

When the new shower uses the same drain and supply lines, the job stays simple. Moving the drain or valve adds labor and time.

Structural and subfloor repairs

Once the old tub comes out, we sometimes find soft subfloor or framing damage. That is a repair, not a surprise markup, and we tell you about it as soon as we see it.

Safety and comfort features

Grab bars, a built-in seat and slip-resistant flooring are modest additions and a big part of why many people convert in the first place. See our accessible bathroom remodel page for ideas.

Bathroom remodel cost by size: 5x7, 5x10 and master baths

People often search for the cost of a 5x7 or 5x10 bathroom remodel, or a master bathroom remodel, expecting square footage to set the price. In practice, scope matters more than size. Full remodels generally start around $18,000 and often run to $30,000 or more, while a shower-only project in the same room costs far less.

  • Small bathrooms (around 5x7): Often a good fit for a walk-in shower conversion, since the tub or shower takes up a large part of the room.
  • Mid-size bathrooms (around 5x10): More room for a full remodel, but a shower-only project can still be the smartest value.
  • Master bathrooms: Usually the widest range, because garden tubs, double vanities and larger showers all change the scope.

Hidden costs to ask about

  • Removal and disposal of the old tub and surround
  • Repairs to the subfloor or framing
  • Upgraded valves or shower fixtures
  • Permits, where required
  • Patching and painting around the new shower

Ask every contractor whether these are included in the quote. Ours is one clear price with no pressure to decide on the spot.

How to save on a tub-to-shower conversion

  • Keep the plumbing where it is. Reusing the existing connections keeps the project simple.
  • Choose seamless acrylic walls. They install faster than tile and need no regrouting later.
  • Stick with a standard base size. Custom sizes cost more.
  • Bundle your updates. Doing the shower and safety features in one visit saves a second trip. Our one-day remodel keeps disruption low too.
  • Ask about financing. It lets you spread the cost out.

Professional installation vs. a DIY conversion kit

Conversion kits are widely sold, and the kit itself usually costs less than hiring a pro. The risk is what you can't see: leaks behind the wall, a poorly sloped base or a door that doesn't fit square. Those are the repairs that get expensive. When we install, you get a written workmanship warranty and a crew that does this every week.

Is converting a tub to a shower worth it?

For most of our customers, yes. A walk-in shower is easier to get into, easier to clean and safer for anyone with limited mobility. It also appeals to buyers who want an updated, low-maintenance bathroom. If you are planning to stay in your home, the daily comfort is the biggest return.

How to compare quotes

Comparing three numbers is not the same as comparing three quotes. Ask what is included: materials, labor, disposal, permits and warranty.

How we put this guide together

The price ranges in the tier table are Carolina Bath Solutions' typical Charlotte-area pricing. They are estimates, not a quote, and your written price is set after we see your bathroom. National cost guides, such as This Old House's 2026 guide, often publish lower averages because they include prefabricated swaps and different scopes of work. The factors above come from the projects we do every week across Charlotte, Ballantyne, Matthews, Huntersville, Concord, Gastonia and nearby towns.
