Bath Fitter vs Tile: What an Acrylic Liner Covers and Hides

The bath fitter vs tile question is a choice between an acrylic liner system made to fit your existing tub and walls, and a tiled shower built from the studs out. Choosing between them? A liner is usually faster and costs less upfront. A full tile shower rebuild runs $5,000 to $7,000+ in Greater Boston, and a tub surround retile runs $4,300 to $5,000 (as of 2026 pricing). In return, the walls get opened, the damage behind them gets fixed, and you get any size or style.

Key Takeaways

• Liners are a category, not one company: Bath Fitter and Re-Bath are well-known names. Methods and warranties vary, so ask each one.
• A liner is a cover, not a repair: rot or leak damage behind an old tub stays there unless someone opens the wall.
• Tile starts at the studs: we remove the old walls, check the framing, then waterproof with RedGard.
• Tile cost: a full shower rebuild runs $5,000 to $7,000+ and a tub surround retile $4,300 to $5,000 (based on current Greater Boston rates). You buy the tile.
• Liners have a place: rentals, tight budgets and quick turnovers.

Bath Fitter vs Tile: How Does an Acrylic Liner Compare to a Tiled Shower?

An acrylic liner trades custom work for speed and a lower upfront price. A tiled shower trades speed for a full rebuild, a custom look and repairs you can make one piece at a time.

What is an acrylic liner system?

An acrylic liner system is a molded acrylic tub shell and wall panels made to fit an existing bathtub or shower. Depending on the company and the job, it may go over the old tub and walls or replace them. The surface is smooth, non-porous and has no grout lines.

What Does a Liner Cover Up (and What Does It Not Fix)?

A liner covers the surface you can see. It does not fix rot, mold or leaks that are already behind or under the old tub. If the wall is not opened, nobody sees the framing.

Problems a Liner Cannot Reach

• Rotted studs or sill plates: years of water through cracked grout can soften the framing behind the tile.
• Soft subfloor: a leaking drain or overflow can rot the floor under the tub.
• Mold in the wall cavity: it grows on wet drywall and wood, out of sight.
• A failed waterproof layer: old tub walls often have tile over plain drywall with no membrane at all.

Signs you have one of these: loose tiles near the tub, a stain on the ceiling below, a soft spot by the tub, or a musty smell. If you see any of them, the wall needs to open no matter what finish goes on next.

Questions to Ask Any Liner Company

These questions are fair to ask any installer, us included. Get the answers in writing.

1. Does the old tub come out, or does the liner go over it?
2. Do the old wall tiles come off? If not, how do you check the wall behind them?
3. What happens if you find rot or mold? Who fixes it, and how is it priced?
4. What does the warranty cover? Is it the product, the labor or both?
5. Who does the plumbing? Ask if the valve trim, drain and overflow are part of the job.

Clear answers mean you can compare quotes fairly. Vague answers are a reason to keep looking.

What We Do Instead

On a tile job, the walls come down to the studs. We fix any rot, hang cement backer board and roll RedGard over every seam and corner. For a walk-in shower, the floor gets a Schluter Kerdi tray or a sloped mud pan, and we connect the Kerdi drain ourselves. Our redgard vs kerdi guide explains why we use liquid waterproofing on walls. For the full build, see tile shower installation.

Bath Fitter vs Tile: What Does Each Cost Over 15 Years?

Over 15 years, the real cost is the upfront price plus upkeep, repairs and the cost of changing your mind. A liner usually wins on day one. Tile can close the gap over time, mostly through cheaper repairs.

We do not have verified prices for liner companies, so we will not guess at them. Use this checklist to compare a liner quote with a tile quote:

Ask the liner company for the warranty in writing, including what it covers and who honors it. On tile, ask about the installer's warranty, the waterproofing product and who buys the tile. With us, you buy the tile and we recommend suppliers. Extras like a recessed niche are priced up front, at $400 to install. See our guide to shower niche dimensions for sizes.

When Does a Liner Make Sense?

A liner makes sense when the walls behind the tub are sound and low cost or speed matters more than a custom look. We say this plainly, even though we build tile showers.

• Rentals: a fast, clean shower between tenants.
• Tight budgets: when the money has to cover other repairs first.
• Selling soon: a fresh surface for listing photos.
• Sound walls: tile that is tight, no stains below, no soft spots.

Tile makes more sense in these cases:

• Signs of a leak: loose tile, a ceiling stain or a soft floor.
• Layout changes: a tub to shower conversion, a niche or a bench.
• A home you will keep: where long life and repairs matter more than day-one price.

Bath Fitter vs Tile: Which Should You Choose?

• Lowest upfront cost and fastest job: an acrylic liner, if the walls are sound.
• Longest life and easiest repairs: tile over RedGard.
• Most style choice: tile in any size or pattern, with Laticrete Permacolor grout and a metal edge finished to match.
• Least cleaning: a liner, or large-format porcelain with fewer grout lines.
