Home Design Consultation & Lifetime Warranty Details for Your Bathroom Remodel
A full bathroom remodel typically runs about $8,000 to $30,000, and a tub-to-shower conversion often lands around $5,000 to $15,000. An in-home design consultation is the appointment where a remodeler measures your space, shows product options, and prices the job. This guide explains what that consultation covers and what a "lifetime" warranty actually protects.

Who this is for and what you are deciding
You own a home with a bathtub-shower that is roughly 20 years old, and water is escaping underneath. You want a number and you want options. That is the exact spot most callers are in: "I'm just looking for a quote," or "I've got a leaky shower."
The first decision is scope. You are choosing between three paths:
- Replace like-for-like. Swap the old tub-shower for a new tub-shower unit. Fastest, lowest cost.
- Convert. Remove the tub and install a walk-in shower. Popular with owners planning to age in place.
- Full remodel. New surround, floor, vanity, fixtures, and sometimes layout changes.
A leak underneath does not automatically mean the whole bathroom is ruined. It usually means the drain connection, the tub's caulk-and-flange seal, or the subfloor has failed. But you cannot price the fix without knowing whether water reached the joists. That is what the consultation is for.
The second decision is who does it. A weekend-handy owner can re-caulk a seam. A rotted subfloor and a hidden drain leak are not a caulk problem. Later in this guide, you will find clear criteria for that call.
You do not need to know the shower type before you book. Consultants expect "I want to explore options." That is a normal, correct answer. You are gathering information, not signing anything. Reading this first means you walk into the appointment knowing what a fair range looks like.
What homeowners misunderstand about the consultation and "lifetime" warranty
This is the gap that costs people money. Two ideas get misread constantly: what the in-home consultation is, and what "lifetime warranty" actually covers.
The consultation is a sales-and-measure visit, not a diagnosis-only visit
An in-home design consultation is an appointment where a remodeler measures your bathroom, inspects the leak area, shows product samples, and hands you a written price. Expect it to run 60 to 120 minutes. The company will ask how long you have owned the home, how many stories it has, and whether it is single-family. Those questions size the job and the crew's access — not a credit check. They may also ask your name, address, and a phone number to schedule and to send the written price; that is routine intake, not a commitment.
Companies want all decision-makers present because they present a price at the end. That is normal. You are never obligated to accept it. Get the price in writing and compare it against another remodeler's number.
"Lifetime warranty" is a specific, limited promise — read the noun it modifies
"Lifetime" almost never means every part, forever, no matter what. Warranties split into pieces:
- Product/material warranty. Often covers the acrylic or solid-surface shower wall against cracking, peeling, and staining. This is the part most often labeled "lifetime."
- Labor/workmanship warranty. Covers the installer's work — leaks, bad seals. This is frequently 1 to 10 years, not lifetime.
- Whose lifetime? Ask if it means the product's expected life, your ownership, or the original buyer only. Many are non-transferable, so they end when you sell.
Ask three questions: What exactly is covered? Is it transferable to the next owner? Who pays labor on a warranty repair? A "lifetime" material warranty that still charges you a service call for a leak is a very different promise than it sounds.
Signs your 20-year-old tub-shower leak is more than a caulk problem
A leak underneath the tub tells you water is getting past a seal and reaching the subfloor. The job is figuring out where and how far. Look for these signs before the consultation so you can describe them accurately.
- Soft or spongy floor next to the tub, or tile that flexes when you step on it. That points to a subfloor already softened by moisture.
- Stains on the ceiling below the bathroom, or in the basement joists. This confirms water has traveled down.
- Musty smell that does not clear with ventilation. Trapped moisture feeds mold behind the wall.
- Peeling caulk or grout cracks where the tub meets the wall or floor. A common entry point on 20-year-old units.
- Loose faucet or overflow plate. The overflow gasket and drain shoe are frequent hidden leak sources on older tubs.
Humid summers and freeze-thaw winters accelerate this. Warm, damp air keeps wall cavities from drying out, and temperature swings crack aging grout. A 20-year-old surround has usually lost its caulk flexibility.
Here is the mechanism that matters: a tub leak rarely stays a tub leak. Water follows gravity into the subfloor, then the framing. Left alone, it rots plywood and can reach the joists. That is why a $300 re-caulk sometimes turns into a $4,000 subfloor and framing repair — the water had a head start. Documenting these signs helps the remodeler price the real job, not a guess.
What actually works — and when DIY fails
Match the fix to the failure. The wrong fix on a hidden leak just buys time while the damage grows.
Surface reseal — works only for a fresh, minor seal failure
If the leak is new and the floor is still solid, removing old caulk and applying new 100% silicone at the tub-to-wall and tub-to-floor joints can stop it. This is genuine DIY territory. Use silicone, not acrylic latex, in a wet zone.
Drain and overflow rebuild — semi-technical
If water shows only when the tub is full, the overflow gasket or drain shoe is often the culprit. Replacing them is doable but requires access below the tub. In a slab or tight framing, that access may not exist.
Replacement or conversion — the durable fix for a 20-year-old unit
When the surround is aged and the subfloor is compromised, replacement is the honest answer. Options include:
- New tub-shower combo — keeps a bathing option.
- Tub-to-shower conversion — removes the tub for a walk-in shower.
- Full remodel — replaces surround, floor, and fixtures together.
Why DIY fails here
Three failure modes trip up homeowners. First, they seal the surface while water keeps entering through the drain — the leak "returns" in weeks. Second, they cover soft subfloor with new tile, trapping rot. Third, they skip the moisture barrier behind the wall, so mold grows unseen. A professional opens the wall, dries or replaces the framing, installs a proper waterproof membrane, then finishes. For a comparison of shower routes, see the walk-in shower vs. tub guide.
DIY vs. calling a professional — a decision you can act on
Use these criteria to decide before you spend a dollar.
Handle it yourself when all of these are true
- The leak started recently, not months ago.
- The floor near the tub is firm — no sponginess, no flex.
- No stains on the ceiling or joists below.
- No musty smell.
- The problem is clearly a caulk seam, not the drain.
That is a reseal. Cost is a tube of silicone and an afternoon.
Call a professional when any of these is true
- The subfloor feels soft or moves.
- You see water damage below the bathroom.
- The unit is 20 years old and the surround is failing.
- The leak returns after you reseal it.
- You want to change the layout or convert the tub to a shower.
The doubt callers voice most is "Is the price fair, and do I even need a pro?" Fair means you compared at least two written prices for the same scope. If two remodelers both open the wall, replace the subfloor, and install a warrantied surround, their numbers should sit in the same neighborhood. A number far below the others usually skips the subfloor or the moisture barrier — the exact steps that make the repair last.
On urgency: a slow leak is not a same-day emergency, but every week of soaking adds framing damage. Weeks matter, not hours. To vet whoever you call, use the bathroom remodeler vetting checklist.
Permits, licensing, and climate to check locally
Rules depend on your city and the work's scope. Confirm the facts with the right local authority before work begins.
Permits
A like-for-like fixture swap often needs no permit. Once you move plumbing, alter framing, or change the drain location, most jurisdictions require a plumbing and/or building permit. Permit fees and requirements vary by city — check your local building department's fee schedule (for example, a metro Department of Codes & Regulations or your county's building inspection office). Do not take a contractor's word that "no permit is needed" for a job that moves plumbing.
Licensing
Plumbing work is typically regulated at the state level by a division of plumbing under a housing or construction authority. Ask your remodeler which licensed plumber will perform the drain and supply work, and confirm the license is current. For consumer disputes, your state Attorney General's Consumer Protection Division is the authority to contact.
Climate realities
Humid summers slow drying inside wall cavities, so a proper vapor barrier and a working exhaust fan matter more than in a dry climate. Winter freeze-thaw cycles crack aging grout and caulk — a chief reason 20-year-old surrounds start leaking. Older homes more often have a single tub-shower and tighter framing, which can limit under-tub access and nudge you toward replacement over a drain rebuild.
Keep every document. Written scope, permit, license number, and warranty terms are your protection if a leak recurs after the work.
Cost factors: what moves the price
Treat every figure as a national published range, then let these factors explain where your job lands.
- Reseal only: materials cost, roughly a tube of silicone.
- Tub-to-shower conversion: commonly about $5,000 to $15,000 nationally.
- Full bathroom remodel: commonly about $8,000 to $30,000 nationally, higher for large or luxury baths.
What drives the price:
- Hidden damage. Subfloor and framing repair is the single biggest surprise on a 20-year-old leaking tub. You cannot fully price it until the wall opens.
- Material grade. Acrylic surrounds cost less than tile; tile adds labor for waterproofing and grout.
- Plumbing changes. Moving a drain or valve adds licensed-plumber hours and possibly a permit.
- Access. Second-story bathrooms and tight framing raise labor.
- Fixtures and glass. Frameless glass, custom vanities, and premium valves push the total up.
- Warranty scope. A transferable, labor-inclusive warranty may raise the quoted price — often worth it for a wet zone.
To fairly compare quotes, make each remodeler price the same scope: leak diagnosis, subfloor repair if needed, moisture barrier, the surround, and written warranty terms. Then the numbers mean something. For deeper ranges, see the bathroom remodel cost guide and the tub-to-shower conversion planning page.
Common questions
Do I have to know what shower I want before the consultation?
No. "I want to explore options" is a normal, expected answer. The consultant brings samples and helps you choose based on your space, your leak, and your budget.
Why do they ask how long I've owned my home and how many stories it has?
Those questions size the job and crew access, not your finances. Ownership length and story count help them estimate framing conditions and labor for reaching the bathroom.
Does a lifetime warranty cover the leak if it comes back?
Only if the warranty includes labor and workmanship, not just the material. Ask whether repairs include labor, whether it is transferable, and exactly which parts are covered before you sign.
Is my leaking tub my responsibility or the installer's?
On a 20-year-old unit past any warranty, it is yours. On recent work still under a labor warranty, the installer should cover a seal or workmanship failure — confirm the term length in writing.
How urgent is a slow leak under the tub?
Not same-day, but do not wait months. Every week of soaking adds subfloor and framing damage, which raises the eventual repair cost. Act within weeks, not hours.
How do I know a quote is fair?
Compare at least two written prices for the identical scope — leak diagnosis, subfloor repair, moisture barrier, surround, and warranty terms. A number far below the rest usually skips a step that makes the fix last.
