Guests prefer showers. Brands are moving that way. The math seems obvious. But after four decades and over a million hotel bathroom renovations, we’ve watched “obvious” decisions quietly turn into the most expensive line item on a PIP — a Property Improvement Plan, the formal list of required upgrades a franchise brand issues to hotel owners, usually with a deadline. Tub-to-shower conversions are the right call in some buildings — and a costly mistake in others. The difference usually comes down to what’s behind the walls.
What a Tub-to-Shower Conversion Actually Involves
A tub-to-shower conversion means removing the existing tub entirely and reconfiguring the shower area to create a walk-in or barrier-free shower in its place. Done well, it’s a genuine upgrade. Done without accounting for what’s behind the walls, it can turn a routine bathroom refresh into a multi-week construction project per room.
The work typically involves:
-
Demo and disposal of the tub and surrounding tile or surround
-
Drain relocation (the tub drain and a shower drain are rarely in the same place)
-
Floor waterproofing, slope, and surface replacement
-
Wall system replacement
-
New fixtures, door or barrier, and finishing
None of that is exotic work. But each step assumes the underlying structure — plumbing, subfloor, walls — is in a condition that can support it cleanly.
In newer buildings, it usually is. In older ones, that assumption gets tested fast.
When It Is the Right Call
A tub-to-shower conversion makes the most sense when:
The building is newer or recently updated.
Post-2000 construction typically has plumbing runs and subfloor conditions that make conversion straightforward. Drain relocation is manageable, waterproofing is predictable, and demo doesn’t uncover a decade of surprises.
Your brand standards allow or require it.
Some franchise brands standards — the rules a hotel franchise sets for how a property must look and function — have moved toward walk-in showers as a compliant option or even a preferred spec. If your PIP specifically calls for a shower conversion, that’s your answer.
Your mix justifies it.
Extended-stay and business-focused properties serving solo travelers have less need for tubs than family-oriented or leisure properties. Knowing your actual occupancy mix before committing to a full conversion across the property is worth the five minutes it takes.
You have a disciplined phasing plan.
Conversions require more room downtime per bathroom than a liner-and-surround installation. If the project plan accounts for that — with a hard cap on rooms out at any given time and a repeatable room-turn rhythm — the operational hit is manageable.
When It Isn’t the Right Call
This is the part that doesn’t come up enough in the initial conversation.
Older buildings carry real risk.
In properties built before 1980, opening walls for a tub-to-shower conversion means potentially encountering asbestos-containing materials in tile adhesive, drywall compound, or floor tile. Lead paint is another consideration. The moment those materials are disturbed, the project moves from renovation to abatement — a different regulatory category with its own costs, timeline, and subcontractor requirements.
None of this makes conversion impossible. It makes it more expensive and more complicated than the initial scope suggested. If your building was constructed in that era, the honest pre-planning question is: have we accounted for abatement costs? If the answer is no, the budget conversation needs to happen before demo does.
Plumbing can be the hidden variable.
Drain relocation in older stack systems isn’t always clean. Depending on how the building is plumbed, getting the drain to the right location for a properly sloped shower floor can require opening the ceiling of the room below, coordinating with that room’s schedule, and dealing with materials that weren’t meant to be touched. In a mid-renovation operating hotel, that’s a significant complication.
Not every room type needs it.
Suites, ADA-accessible rooms, and family-configured rooms often need to retain tub access for compliance or market reasons. A blanket conversion approach across all room types can create problems that are expensive to reverse.
The Alternative Worth Knowing
In a lot of cases — particularly in older buildings — the smarter path is encapsulation rather than demolition. A custom acrylic bathtub liner goes over the existing tub; acrylic wall surrounds go over the existing walls. The room looks new. It returns to service fast. And no one opens a wall to find out what 1975 left behind. Learn more about hotel bathroom renovation options that skip the demo risk entirely.
That’s not a compromise. In the right building, it’s the correct call — and it often delivers a brand-compliant result at significantly lower cost and room downtime than a full tub-to-shower conversion.
AmBath Direct is built around exactly this approach. It’s not for every property, but it’s the right answer more often than most operators realize going into a PIP.
What We Tell Owners When They Ask
The honest answer is: it depends on the building, the brand spec, the room mix, and what you find when you open the walls.
What we don’t do is tell you conversion is always straightforward — or always a problem — without looking at the specifics. The properties that have the worst PIP experiences are usually the ones that made a big scope decision based on the trend rather than the building.
If you’re weighing a tub-to-shower conversion for your property, we’re happy to talk through the specifics before a decision gets made. That conversation is free. The surprises you avoid by having it are not.
