Tub to Shower Conversion in Knoxville: Options, Cost and Process

A tub to shower conversion swaps the bathtub you rarely use for a shower that is easier to step into, easier to clean and better suited to how you live now. Many Knoxville homeowners call us after years of climbing over a tub wall just to rinse off. If that sounds like your bathroom, this guide covers your options, the process and what drives the price. You can also see our full Knoxville bathroom remodeling services.

Quick answer: Most professional tub to shower conversion projects cost about $2,000 to $12,000 nationally, according to This Old House, and take about 3 to 7 days. Acrylic panel systems sit at the lower end. Tile and curbless showers cost more. Your exact price depends on your bathroom, so a free in-home estimate is the only way to know.

This post is about converting a tub you already have. If you are planning a brand-new shower from scratch, our walk-in shower cost guide covers that. Here we focus on what happens when the tub comes out, what your choices are, and who this upgrade is right for.

Tub to Shower Conversion Options for Your Bathroom

A standard tub space is usually about 60 inches long and 30 to 32 inches deep. That footprint gives you a few good paths. The right one depends on your budget, how long you plan to stay in the house, and who uses the bathroom every day. Below are the three most common choices we see in East Tennessee homes, from the simplest to the most involved.

Acrylic Shower Systems

Acrylic or fiberglass panel systems go over a properly prepared wall and pair with a new shower base. There are no grout lines to scrub, so cleaning is quick. This is often the lowest-cost path and the fastest to install. American Home is an authorized Bath Planet dealer, and Bath Planet acrylic systems are made for this kind of tub to shower conversion. You can pick wall patterns, colors, shelves, grab bars and a fold-down seat.

Tiled Walk-In Shower

A tiled shower gives you the most design choice. You can pick porcelain, ceramic or stone, add a niche (a built-in shelf in the wall) and choose a pattern you love. Tile takes longer because each layer needs time to set. It also needs a proper waterproof layer behind it to keep water out of your walls. Tile costs more than panels, and grout needs sealing and cleaning over the years.

Low-Threshold and Curbless Showers

A low-threshold base has a short lip, often just a few inches tall, so you can step over it with ease. A curbless shower has no lip at all. The floor slopes gently to the drain. Curbless is the best choice for wheelchairs and walkers, but it costs the most. The floor often has to be lowered or rebuilt so water stays in the shower. Many homeowners pick a low-threshold base as a middle ground.

Tub to Shower Conversion Cost: National Ranges for 2026

Here are national ranges from the This Old House tub to shower conversion cost guide, updated in 2026. These are national averages, not American Home prices. East Tennessee prices vary from home to home.

• Typical full project: $2,000 to $12,000
• Prefab acrylic or fiberglass panels: $2,000 to $6,000
• Walk-in shower: $5,000 to $12,000
• Tile shower: $6,000 to $12,000
• Curbless shower: $8,000 to $15,000

Add-On Costs to Plan For

Some line items sit on top of the shower itself. This Old House lists these national ranges:

• Framed glass doors: $400 to $1,200
• Frameless glass: $1,200 to $3,000
• Moving the drain: $900 to $1,100
• New or upgraded shower valve: $700 to $1,200
• Tub removal and disposal: $300 to $1,200

They also suggest setting aside 10% to 20% for surprises. In a tub to shower conversion, the surprise is usually what’s hiding under the old tub. For a rough starting number, try our home remodeling cost estimate calculator. The only way to know your real price is a free in-home estimate.

What Raises or Lowers Your Tub to Shower Conversion Cost

Two bathrooms that look the same can get very different prices. These are the factors that move the number the most.

1. Shower type. Acrylic panels cost less than tile. Curbless costs the most because the floor changes.
2. Plumbing changes. Keeping the drain and valve where they are saves money. Moving them adds labor.
3. Glass choice. A curtain costs the least. Framed doors are in the middle. Frameless glass is the priciest.
4. Hidden damage. Rotted subfloor or wet framing must be fixed before the new shower goes in.
5. Extras. Grab bars, a seat, a niche, a handheld sprayer and better lighting each add a little.
6. Access. A second-floor bath or a tight hallway can add time for removal and delivery.

The good news is that you control many of these. If budget matters most, keep the plumbing in place and choose panels. If safety matters most, put your money into a low threshold, a seat and grab bars first.

Is a Tub to Shower Conversion Right for You?

This upgrade is a great fit for many homes, but not every one. It tends to make the most sense if:

• You or a family member has trouble stepping over the tub wall.
• You plan to stay in your home as you get older.
• Nobody in the house takes baths anymore.
• You want a bathroom that is faster to clean.
• Your current tub is cracked, stained or worn out.

It may not be right if you have small children who need baths, or if it’s the only tub in the house and you plan to sell soon. Some buyers with young kids want at least one tub. If you have two bathrooms, converting one and keeping a tub in the other is often a good balance.

Safety is a big reason people make the switch. A low step into the shower, a seat and solid grab bars are some of the simplest ways to lower the risk of a slip. The CDC shares helpful fall prevention tips for older adults and their families.

The Tub to Shower Conversion Process, Day by Day

Most professional conversions take about 3 to 7 days, per This Old House. Panel systems are usually on the short end. Tile and curbless jobs take longer. Here is what a typical project looks like. Your schedule may differ based on your bathroom and the shower you choose. If you have a second bathroom, you can usually keep using it during the work.

Day 1: Protect and Remove

The installers cover floors and the path to the bathroom. The water is shut off. The old tub, surround and fixtures come out and are hauled away. Once the tub is gone, the floor and walls are checked for water damage, soft spots or mold. If repairs are needed, this is when you will hear about them, before anything new goes in.

Days 2 to 3: Plumbing, Repairs and the New Base

Any rotted wood is replaced. The drain is adjusted to fit the new shower base, and the valve is updated if needed. Blocking (extra wood inside the wall) goes in where grab bars and a seat will mount. Then the shower base is set level and secured. A level base matters because it keeps water flowing to the drain instead of pooling in a corner.

Days 3 to 7: Walls, Glass and Finish

For an acrylic system, the wall panels go up, and trim and fixtures are installed. For tile, the waterproof layer, tile and grout each need time, which is why tile takes more days. Glass doors are often the last big piece, since frameless glass is usually measured after the walls are done. Last comes caulking, cleanup and a walkthrough with you.

What East Tennessee Homes Need From a New Shower

Our area brings a few things to watch for. Long, humid summers mean bathrooms stay damp. A shower without good airflow can grow mold on ceilings and in corners. Make sure your bathroom fan works, vents to the outside, and runs for a while after each shower. A conversion is a good time to upgrade a weak or noisy fan.

Many homes around Knoxville, Oak Ridge and Maryville are older ranch homes. Old tubs in these homes often hide slow leaks. It’s common to find a soft subfloor or worn framing when the tub comes out. A good contractor will check this and tell you before covering anything up.

Some older homes also have aging pipes and valves. A tub to shower conversion is a smart time to replace an old valve, since the wall is already open. If your home sits on a slab, or on a hillside lot with a tight crawl space, drain changes can take more work. These are normal issues, and a careful estimate should point them out.

Mistakes to Avoid and Questions to Ask Your Contractor

A tub to shower conversion is a modest project, but a few mistakes can cause leaks or regret later. Watch out for these:

• Covering up damage. New panels over soft walls or a wet floor will fail.
• Skipping blocking. Grab bars need solid wood behind them, not just drywall.
• Choosing a base that is too tall. If easy access is the goal, ask about a low threshold.
• Forgetting the fan. A new shower in a room with weak airflow can still grow mold.
• Comparing quotes that are not equal. Make sure each one includes the same base, walls, glass and plumbing work.

Questions to Ask Before You Sign

• What is included in the price, and what could cost extra?
• What happens if you find rot when the tub comes out?
• Will you need to move the drain or replace the valve?
• How many days will my bathroom be out of use?
• What warranty comes with the product and the work?
• Are you licensed in Tennessee, and do you carry insurance?

A good contractor will answer these clearly and put the details in writing.
