The tub-shower combo is the hardest-working fixture in most homes, and when it starts to look dated or leak, the whole bathroom feels tired. A bathtub shower remodel can range from a one-day surround swap to a full gut that relocates plumbing, so the first job is figuring out which project you actually need. Knowing the real scope up front keeps your budget honest and prevents the classic mistake of tearing into a wall for a job that a $1,200 refresh would have solved.
Four Levels of Remodel
These projects fall into clear tiers, and the price gaps between them are large.
- Refinish/reglaze: $400 to $800, restores a worn tub surface in a day
- Surround replacement: $1,500 to $4,000, new walls and fixtures, tub stays
- Tub-to-shower conversion: $3,500 to $10,000, remove tub, build walk-in shower
- Full gut remodel: $8,000 to $20,000+, new plumbing, tile, and layout
Match the tier to the actual problem. A structurally sound tub with dated color needs reglazing, not demolition. A leaking valve behind cracked tile needs the wall open.
Should You Keep the Tub or Convert to a Shower
This is the pivotal decision. Keep at least one bathtub in the house if you have young children or plan to sell to families, because appraisers and buyers still expect a soaking option somewhere in the home. Convert to a walk-in shower in a primary bath when the tub sits unused, when aging-in-place safety matters, or when a curbless shower would make the space feel larger. A tub-to-shower conversion typically runs $3,500 to $8,000 and instantly modernizes the room, but do not eliminate your only tub without weighing resale.
Surround and Wall Material Choices
Acrylic and Fiberglass Panels
Prefabricated acrylic surrounds install in a day, resist mold, and cost $300 to $1,500 for the panels. They are the fastest, most waterproof option and the go-to for one-day remodel companies. The trade-off is a less custom look.
Tile
Ceramic or porcelain tile over a proper waterproof membrane delivers the premium, fully custom finish for $7 to $25 per square foot installed. It demands skilled labor and a waterproofing system like a foam board or liquid membrane behind it, or moisture will destroy the wall.
Solid Surface and Cultured Marble
Seamless solid-surface panels split the difference at $1,000 to $3,000, offering a joint-free wall that cleans easily without grout lines.
What Drives the Cost
Several factors decide where your bathtub shower remodel lands. Moving plumbing, relocating the drain or valve, is the single biggest budget-buster because it means opening walls or the floor and often calls a licensed plumber. Premium fixtures like a thermostatic shower valve, a rainfall head, or frameless glass add hundreds to thousands. Structural surprises behind the old tile, rotted studs, mold, or outdated galvanized pipe, routinely add $500 to $2,000 once the wall is open. Always keep a 15 to 20 percent contingency.
Typical Timeline
Plan your household’s shower schedule around the scope.
- Reglaze: 1 day, plus 24 to 48 hours cure before use
- Acrylic surround swap: 1 to 2 days
- Tub-to-shower conversion: 3 to 5 days
- Full gut with tile: 1 to 3 weeks including cure and inspection time
Tile jobs take longest because thinset, grout, and waterproofing each need drying time you cannot rush without risking failure.
What to DIY and What to Hire Out
Skilled DIYers can handle demolition, an acrylic surround install, new trim, and painting, saving a meaningful chunk of labor. Leave three things to licensed pros: any plumbing that moves a drain or valve, electrical work for new lighting or an exhaust fan, and full tile waterproofing if you are not experienced, because a hidden leak behind new tile is the most expensive failure in the whole project. A hybrid approach, doing demo and finish work yourself while hiring the plumber and tile-setter, often lands the best value.
Waterproofing Is Non-Negotiable
More remodels fail from water intrusion than from anything else. Behind any tile shower wall you need a continuous waterproof layer: a liquid-applied membrane, a foam backer board system like Schluter-Kerdi, or at minimum a proper vapor barrier and cement board, never plain drywall or greenboard in the wet zone. Slope the shower floor a quarter-inch per foot toward the drain, and seal every change of plane with the manufacturer’s banding. Getting this layer right is what separates a shower that lasts 20 years from one that grows mold in two.
Smart Upgrades Worth the Money
A few additions pay you back in comfort and resale. A pressure-balancing or thermostatic valve prevents scalding when someone flushes elsewhere in the house. A built-in niche keeps bottles off the tub ledge and costs little when done during the remodel. A quiet 80 to 110 CFM exhaust fan protects your new walls from the moisture that causes mold. Slip-resistant flooring and a grab bar blocked into the studs add safety without looking clinical if you choose modern finishes.
Getting Started
Begin by diagnosing whether your problem is cosmetic or structural, then pick the matching tier rather than defaulting to a full gut. Gather three itemized bids for anything beyond a surround swap, confirm the waterproofing system in writing, and decide early whether keeping a tub matters for your household and resale. A well-planned bathroom remodel not only fixes the daily annoyances but returns a solid share of its cost at sale, especially when the work is done right the first time.
