A tired bathtub can drag down a whole bathroom. Chipped enamel, a stained surround, an avocado-green relic from the original build, or a deep soaker nobody in the house actually uses anymore. The question most people start with isn’t “which tub do I want,” it’s “what are my real choices, and how much is each one going to cost me?”
The honest answer is that “bathtub remodel” covers four very different projects, and they range from a few hundred dollars to a small kitchen’s worth of money. This guide walks through each one, what it costs, where it makes sense, and the Arizona-specific things (hard water, resale, aging in place) that should steer your decision.
Quick answer: A bathtub remodel can mean refinishing the tub you have, dropping in a liner, fully replacing the tub and surround, or converting the tub to a walk-in shower. Refinishing runs a few hundred dollars; a full replacement or conversion typically lands in the low-to-mid four figures, depending on plumbing, tile, and the fixtures you choose.
Key takeaways
- There are four common paths: refinish, reline, replace, or convert to a shower. Each solves a different problem at a different price.
- Refinishing is cheapest and fastest but the shortest-lived; full replacement lasts longest and costs the most.
- Hard water is the deciding factor for Arizona tub materials and finishes, not looks alone.
- Keep at least one bathtub in the home if resale matters, especially for family buyers.
- A tub-to-shower conversion is often the best move in a rarely-used second bathroom.
What is a bathtub remodel?
A bathtub remodel is any project that updates or replaces your existing tub and the wall area around it, ranging from a surface refresh to a full tear-out. It’s useful to think of it as a spectrum rather than one job.
- Refinishing (reglazing): A pro cleans, repairs, primes, and sprays a new coating over your existing tub. The tub stays put. Best for surface damage like chips, stains, and dated color.
- Bathtub liner: A custom acrylic shell is molded to fit over your old tub. It hides wear without a tear-out but seals a used tub underneath.
- Full replacement: The old tub comes out and a new one goes in, usually with a new surround. This is the only option that also fixes what’s behind the wall, like old plumbing or hidden water damage.
- Tub-to-shower conversion: The tub is removed and the space becomes a curbed or curbless walk-in shower. Popular for accessibility and for bathrooms nobody bathes in.
If your walls, floor, or plumbing are also getting touched, you’ve crossed from a tub project into a broader bathroom remodel, which changes both the timeline and the budget.
The four options, side by side
Before you price anything, figure out which of the four you actually need. The wrong starting point is the most expensive mistake here. A gorgeous new freestanding tub does nothing for you if the real problem was a rotted subfloor, and a refinish over a cracked tub just buys you a few years.
Match the fix to the problem. Cosmetic issue and a sound tub? Refinishing or a liner is enough. Failing tub, old plumbing, or you’re changing the layout? You want a replacement or a conversion. The comparison table further down lays out cost and lifespan so you can weigh them directly.
One Arizona note worth flagging early: our water is hard, and mineral-heavy water is rough on both finishes and fixtures. That reality should shape your material choices as much as your taste does, which is a thread we’ll pick back up below.
Where a design-build remodeler like AZ Granite & Remodeling fits
Once your project crosses from a surface refresh into a real replacement or conversion, you’re coordinating demolition, plumbing, waterproofing, tile, and stone. That’s where a design-build contractor earns its keep, and it’s the lane AZ Granite & Remodeling has worked for over 20 years across the Phoenix Valley.
The practical advantage of a design-build shop is one accountable team instead of a general contractor plus a stone yard plus a tile crew who all point at each other when something goes sideways. AZ Granite works one-on-one with a designer, then handles fabrication and installation in its own Phoenix shop. If you want a stone tub deck, a solid-surface surround, or a shower niche cut to match a vanity top, the same crew measuring your bathroom is cutting the stone in house, so the pieces match and the seams land where they should.
They serve homeowners across North Scottsdale, Desert Ridge, Peoria, Sun City, Anthem, and the surrounding East and West Valley, and the estimate is a free, no-pressure in-home visit. Because they fabricate full slabs anyway, they also keep granite and quartz remnants on hand, which is often enough material for a tub deck or a small surround at a fraction of full-slab cost. If you’re weighing a tub versus a walk-in shower, their shower remodel cost guide for Phoenix breaks down that trade in plain numbers, and you can request an estimate through their contact page.
That’s the paid-pro side of the picture. The rest of this guide stays on the decision itself, whoever you end up hiring.
What each option really costs
Costs swing based on your materials, your plumbing, and how much of the surrounding wall gets opened up. These are general market ranges, not a quote for your bathroom. For a firm number, you need someone to see the space.
- Refinishing: Roughly $300 to $600 for a standard tub. Fast and cheap, but the finish is a coating, so it’s the shortest-lived path.
- Bathtub liner: Often $1,000 to $2,500 installed. Cleaner look than refinishing, but you’re sealing an old tub under acrylic, and water can get trapped if the fit isn’t perfect.
- Full tub and surround replacement: Commonly $3,000 to $8,000+, driven by the tub type, whether you tile the walls, and any plumbing or drywall repair once the wall is open.
- Tub-to-shower conversion: Typically $4,000 to $12,000+, depending on glass, tile, a curb versus curbless base, and drain relocation.
The biggest hidden cost is what’s behind the wall. Original-build bathrooms across the Valley sometimes hide corroded galvanized plumbing or slow leaks that only show up during demo. A good contractor prices honestly for the unknowns instead of lowballing to win the job.

Bathtub remodel options compared
| Option | Typical cost | How long it lasts | Best for | Watch out for |
|---|---|---|---|---|
| Refinish / reglaze | $300–$600 | 5–10 years | Chips, stains, dated color on a sound tub | Coating wears; harsh cleaners shorten it |
| Bathtub liner | $1,000–$2,500 | 10–15 years | Hiding wear without a tear-out | Water trapped under a poor fit |
| Full replacement | $3,000–$8,000+ | 20–30+ years | Failing tubs, old plumbing, new look | Cost jumps if the wall hides damage |
| Tub-to-shower conversion | $4,000–$12,000+ | 20–30+ years | Accessibility, rarely-used tubs | Removing the home’s only tub hurts resale |
Choosing a tub material that survives Arizona water
Material matters more here than in wetter, softer-water states, because hard water leaves mineral scale that dulls finishes and clings to porous surfaces. A few honest trade-offs:
- Acrylic is light, warm to the touch, holds heat well, and resists staining. It’s the practical default for most replacements. It can scratch, but scratches in acrylic can often be buffed out.
- Porcelain-enameled steel or cast iron is hard and classic, but heavy, and once the enamel chips, the exposed metal can rust in our mineral water.
- Solid surface and stone (for decks and surrounds) reads high-end. Sealed properly, natural stone holds up, but it wants routine sealing and non-acidic cleaners to fend off etching and hard-water spots.
Whatever the surface, the fixtures matter too. A water-efficient tub filler and showerhead carrying the EPA WaterSense label saves water without the weak-flow feeling, which is a small line item that pays off over years of desert utility bills.
Should you keep the tub at all?
This is the question people skip and later regret. Keep at least one bathtub in the home if you might sell, especially in family neighborhoods, because a house with zero tubs narrows your buyer pool. Bathing small kids and washing pets are real, boring reasons buyers care.
But if you have a second or third bathroom whose tub sits dry for months, converting it to a walk-in shower is often the smarter remodel. It reclaims usable space and adds accessibility. Falls are the leading cause of injury for older adults, and the bathroom is a common site, per the CDC, so a curbless shower with grab bars is a genuine safety upgrade rather than a style choice. The move most Valley homeowners land on: one tub stays, the rarely-used one becomes a shower.
How long a bathtub remodel takes
Timelines track the option. Refinishing is usually a one-day job plus a day or two of cure time before you use the tub. A liner install is often a day. A full replacement or conversion typically runs several days to two weeks once tile, waterproofing, and cure times are factored in, longer if the wall reveals surprises. If your project is part of a larger renovation, this bathroom remodel timeline for Phoenix sets realistic expectations.
Frequently asked questions
Is it cheaper to refinish or replace a bathtub?
Refinishing is far cheaper up front, usually $300 to $600 versus several thousand for a replacement. But refinishing is a coating that lasts 5 to 10 years, while a new tub lasts decades. If your tub is structurally sound and you only dislike the surface, refinishing wins on cost. If the tub is cracked, leaking, or hiding old plumbing, replacement is the better long-term value.
Do bathtub remodels add resale value?
An updated bathroom generally helps resale, and a clean, modern tub area reads well in listing photos. The bigger resale factor is keeping at least one tub in the home. Removing every bathtub can shrink your buyer pool, especially among families, so weigh a full tub-to-shower conversion carefully if it’s your only tub.
Do I need a permit for a bathtub remodel?
It depends on scope and your city. Swapping a tub in the same spot without moving plumbing often needs little or no permitting, while relocating the drain, altering the layout, or converting to a shower usually does. A licensed local contractor will know your jurisdiction’s rules and pull permits as part of the job, which protects you at resale.
How long does a refinished tub last?
A professionally refinished tub typically holds up 5 to 10 years, sometimes longer with gentle care. Avoid abrasive cleaners, bleach, and bath mats with suction cups, since those are the fastest ways to wear through the coating. DIY kits exist, but they tend to peel sooner than a properly prepped professional spray finish.
What’s the best low-maintenance tub for hard water?
Acrylic is the easiest to live with in Arizona’s hard water. It’s non-porous, resists staining, and mineral scale wipes off more easily than it does from porcelain or unsealed stone. Whatever you choose, a water softener and non-acidic cleaners extend the life of both the tub finish and your fixtures.
Can any bathtub be converted to a walk-in shower?
Most standard alcove tubs convert well because the space and plumbing are already there. The main variables are the drain location, the wall condition once the tub is out, and whether you want a curb or a curbless base. A curbless conversion is more involved because it may require adjusting the floor for proper drainage, so it costs more but improves accessibility.
Is a bathtub liner a good idea?
A liner can be a reasonable middle option when your tub is worn but the walls and plumbing are fine and you want to avoid demolition. The risk is fit. If the acrylic shell doesn’t seal tightly, water can get trapped between the liner and the old tub, leading to odor or mildew. Insist on a custom-molded liner and a professional install rather than a generic drop-in.
