A one-day bathroom remodel is an acrylic liner installed over your existing tub and walls, usually $4,000 to $12,000, and it does not touch the plumbing, subfloor, or anything hidden behind the wall. In older Tampa Bay homes that is exactly where the real problems live. A full bathroom remodel runs $18,000 to $50,000 and actually fixes them, usually in 2 to 4 weeks. CraftLine is a licensed design build contractor, and this page lays out honestly where one-day systems fall short so you can decide with clear information.
One-day remodels are marketed hard on speed and a fixed sticker price. For a newer home with sound plumbing and a flat budget, an overlay can be a reasonable cosmetic fix. The trouble starts in the homes that make up much of Tampa Bay, where what is behind the wall is the part that needs the work.
What a One-Day Remodel Skips
- Corroded plumbing. An overlay tiles right over galvanized and cast-iron drain lines that are common in pre-1960s Tampa and St. Petersburg homes. The lines keep failing under the new acrylic.
- Soft or rotted subfloor. Slow leaks around an old tub rot the subfloor. A liner placed on top hides the damage instead of repairing it.
- Hidden mold. Florida humidity plus a long-term leak grows mold inside the wall cavity. Covering it does not remove it.
- Layout changes. You cannot move a wall, relocate plumbing, or convert a tub to a true curbless walk-in shower with an overlay.
One-Day Overlay vs Full Remodel
| One-day overlay | Full CraftLine remodel | |
|---|---|---|
| Typical cost | $4,000 to $12,000 | $18,000 to $50,000 |
| Timeline | 1 to 3 days | 2 to 4 weeks |
| Fixes plumbing | No | Yes, including re-pipe when needed |
| Repairs subfloor / mold | No | Yes |
| Allows layout change | No | Yes |
| Permitted and inspected | Often not | Yes |

Why This Hits Tampa Bay Homes Especially Hard
Much of the area’s most charming housing is also its oldest plumbing. South Tampa bungalows, St. Petersburg and Gulfport cottages, and Plant City’s historic homes were built when galvanized supply lines and cast-iron drains were standard, and many still have them. Add decades of Florida humidity and the occasional slow leak, and the wall cavity behind a 50-year-old tub is the last place you want to seal up without looking. An overlay buys a few good-looking years and then the original problem resurfaces, often worse and more expensive to reach because it is now behind acrylic.
How a CraftLine Project Works
- Consultation. We open up the right spots, check the plumbing and subfloor, and tell you what is actually there.
- Design and fixed price. You get an itemized scope that includes the repairs an overlay would hide.
- Build. One licensed crew handles demo, plumbing, waterproofing, tile, and finish.
- Walkthrough. We finish the punch list and stand behind the work.

Overlay and Permitted Rebuild, Priced Side by Side
The one-day companies publish a price and the tile contractors publish a price, and nobody puts them in the same table. Here they are, using the installed ranges from our Tampa Bay bathroom cost guide.
| Line | One-Day Overlay | Permitted Rebuild |
|---|---|---|
| Shower or tub surround | Acrylic liner over existing surface, $4,000 to $12,000 all in | Prefabricated acrylic $1,800 to $3,500, or tile shower $4,000 to $7,000, premium tile $7,000 to $12,000 |
| Demolition and haul away | None. The old surface stays | $800 to $1,500 |
| Plumbing | Valve trim swapped, supply and drain untouched | $1,500 to $2,500 same locations, $2,500 to $4,500 if anything moves |
| Waterproofing behind the surface | Not inspected, not replaced | Shower waterproofing and tile, $15 to $25 per square foot |
| Subfloor and framing repair | Not opened, so not found | Repaired at demo, priced as found |
| Electrical, exhaust, lighting | Rarely touched | $1,500 to $3,500 |
| Vanity, top and fixtures | Usually a separate add-on | Vanity $800 to $2,500, quartz top $70 to $130 per sq ft installed, fixtures $800 to $2,000 to install |
| Permit and inspection record | Usually none, because nothing structural moved | Pulled, inspected and on file with your address |
Read the table across and the picture is clear. The overlay is not competing with a full bathroom remodel. It is competing with the shower line item of one, and it is priced at or above what a real tile shower costs, because you are paying for speed and for a sales process rather than for materials and trades.
The Seven Year Math
An overlay bonded to an old substrate is only as good as what is behind it. If it holds for the life of the house, you spent $4,000 to $12,000 and saved weeks of disruption, and that was a fine trade. If it fails at year seven, the sequence is: pull out the liner, discover the condition of the wall and subfloor that nobody looked at in the first place, and then do the permitted rebuild you were choosing between at the start. You paid for both, plus the demo of the first one.
That is the whole argument, and it is an honest one in both directions. The question worth asking a salesperson is not how long the warranty is. It is what the warranty covers when the failure is in the substrate their product was installed over, and who inspects that substrate before installation.
What Florida Adds to the Problem
Tampa Bay is a bad climate for hiding moisture. Interior humidity stays high most of the year, so a slow leak behind an acrylic panel does not dry out between events, it feeds mold. Under Florida law a general contractor cannot perform mold remediation over ten square feet without a licensed remediator, which tells you how seriously the state treats what grows in a wet wall.
The housing stock makes it worse. A large share of Tampa Bay homes from the 1950s through the early 1970s are slab-on-grade with cast iron drain lines under the concrete. Cast iron in this climate is at the end of its service life, and the symptoms show up first at the bathroom. A remodel that opens the floor finds it. An overlay that covers the wall does not, and you get another five to ten years of a pipe you already needed to replace.
There is also a paperwork consequence people forget. Permitted work leaves a record attached to your address. Unpermitted work leaves nothing, and a buyer inspector who spots a liner over an older tub in a house with no bathroom permit on file will ask what is behind it. You will not have an answer.

One-Day Bathroom Remodel FAQ
Is a one-day bathroom remodel ever a good idea?
It can work as a cosmetic update in a newer home with sound plumbing and no hidden damage. In older Tampa Bay homes it usually covers problems that come back.
Why is an overlay cheaper?
Because it skips the work. No demolition, no plumbing repair, no subfloor or mold remediation. You are paying for a surface, not a fixed bathroom.
Does a one-day remodel really take one day?
The install is fast, but many homeowners report it runs longer than promised, and it still leaves any underlying plumbing or structural issue untouched.
How long does a proper bathroom remodel take?
Most full remodels take 2 to 4 weeks. That includes fixing what is behind the wall, not just the surface you see.
What about my old galvanized pipes?
If your Tampa Bay home still has galvanized or cast-iron lines, a remodel is the right time to re-pipe while the walls are open. An overlay simply seals them in.
Does an overlay need a permit in Hillsborough or Pinellas?
Usually not, and that is part of why it can be done in a day. Work that does not move plumbing, alter framing or add circuits generally falls outside the permit requirement. The flip side is that no inspector ever looks at the wall the new surface is bonded to. Every jurisdiction here is slightly different, so we confirm before we start any job.
Can you remove a failed liner and build a real shower?
Yes, and it is a normal job for us. We take out the liner and the surface under it, open the wall, look at the framing, subfloor and supply lines, and rebuild with proper waterproofing and a permitted plumbing rough-in. Pricing depends on what is behind there, which is why we look before we quote a number.
Will an overlay hide an existing leak?
It can hide the evidence of one. A liner covers the stain and the soft grout that were telling you something was wrong. The water keeps going where it was going. If you have seen a stain on the ceiling below, soft flooring at the base of the tub, or a musty smell, that is the reason to open it rather than the reason to cover it.
