Roll-In Showers in Knoxville, TN

This page is about the roll-in entry: what it is, who it is for, why the two published figures are so far apart, what a full accessible build actually contains, and the lines a quote has to separate before two prices can be compared. Every figure here is a published United States range from the 2026 guides named at the foot of the page, not a Knoxville price. We are a free matching service, not a building company: we introduce you to licensed accessibility contractors, and the scope and the priced quote come from the contractor you are introduced to.

What a roll-in shower is, and who it is for

A roll-in shower has no threshold at all: the bathroom floor runs level into the wet area, so a wheelchair, a shower chair or a walker goes in without being lifted over anything. The floor is shaped to fall to the drain rather than sitting behind a raised lip, and the walls carry reinforcement so bars can be fixed where the person actually reaches.

It is the fixture for a household where someone uses a wheelchair or a transfer chair, or where a seated shower is the routine rather than a standing one. Where a person can still step over a low threshold with something to hold, a walk-in shower with a shallow curb may be enough, and it is the cheaper of the two.

What decides the job is not the shower itself but the room around it: the entry, the floor, the drain and the doorway.

The two published bands, and why they are not alternatives

This is the point most pages get wrong, so it is worth being exact about it.

$2,900 - $4,600, averaging $3,800, is the fixture and a straightforward installation. That is a roll-in shower unit set into a bathroom where the floor, the drain and the waterproofing already suit a level entry, as published in Angi's 2026 roll-in shower data. It is the unit and the install. It is not an accessible remodel.

$14,000 - $22,000 is a full roll-in or curbless accessible build. That is the whole wet area, as published by adahomefinder's 2026 guide: the floor structure prepared for a level entry, the drain relocated, the waterproofing carried through the room as a system, the tile, and usually a wider doorway.

One is not a cheaper version of the other. They are different scopes of work, so a quote should say which one it is written against before any number on it can be read.

What a full accessible build contains

Inside the $14,000 - $22,000 band, the money is in the parts of the job nobody sees.

The floor structure. A level entry means either the shower floor is recessed below the room floor or the room floor is built up to it. That is subfloor and framing work, and it is what most of the band rests on.

The drain. Moving a drain in this kind of conversion adds a published $500 - $1,500 of its own on top of the base work, because the plumbing has to follow it.

The waterproofing. A level-entry wet area is waterproofed as a system across the floor and up the walls rather than painted around a base, and that system is a priced part of the job.

The finish. Tile, grout and the shaping of the floor to the drain are labour, and a linear drain along the wall is what makes a single-direction fall practical.

The doorway. A roll-in entry usually needs a wider door, which is quoted separately.

What a roll-in shower quote must itemise

Ask which of the two published bands a quote is written against, then for these as separate lines:

• Whether the price is the fixture and its installation, or a full accessible build of the wet area.
• The floor structure: what is done to create the level entry, and how it is priced if the framing is worse than expected.
• The drain - centre or linear, where it sits, and whether the plumbing is being moved.
• The waterproofing system by name, and whether it covers the whole wet zone.
• Blocking or reinforcement in the walls, including positions for bars not being fitted yet.
• Materials by name: the base or tray, the tile allowance as a rate, the glass, the seat and the valve trim.
• Electrical work for the light, the fan and the valve, and the permit if one is needed.
• The permit fee and who pulls the permit.
• The doorway, if it has to change for a chair.
• Disposal of the old tub or shower, the tile and the debris.
• The workmanship warranty, separately from the product warranty.

Questions to ask the contractor

Ask these on the first visit, and ask for the answers in writing:

• Is this price for the fixture and its installation, or for a full accessible build of the wet area?
• How is the level entry created here - is the floor recessed, is the room floor built up, and what is that work costing?
• Is the drain moving, and what does that add?
• Which waterproofing system is being used, and does it cover the whole wet zone?
• Where will the bars go, and what is behind the wall at each of those positions?
• Does the doorway have to be widened for the chair, and who confirms whether that wall carries load?
• Which permits are needed, and who pulls them?
• What is the sequence, and how long is the bathroom out of use at each stage?

How our aging in place matching service works in Knoxville, TN

Tell us what the bathroom has to do - a wheelchair or transfer chair in the house, a shower that cannot be stepped into, a wet floor that has already caused a slip - and which part of the county you are in: Knoxville, Farragut, West Knoxville, Powell, Karns, Fountain City, Bearden, Halls, Maryville, Alcoa, Clinton, Oak Ridge, Lenoir City and Sevierville.

We introduce you to licensed accessibility contractors whose crews work that area, at no charge. The assessment, the scope and the priced quote come from the contractor you are introduced to - we do not install, inspect or price anything, and we promise nothing about how a job will go. Whether the fixture alone will do or the whole wet area has to be rebuilt is a question for someone standing in the room.
