Columbus Bathroom Remodel: Getting a Tub-to-Shower Conversion Done Right

A bathtub-to-shower conversion can make a Columbus bathroom easier to use, more comfortable, and better suited to your daily routine. But the finished shower is only part of the project. Behind the walls and beneath the floor, careful planning, sound plumbing, and reliable waterproofing help protect your home for years to come.

Whether you’re updating a compact bathroom or planning a broader renovation, here’s what to consider, and what to ask your remodeling contractor, before replacing a tub with a shower.

Start with the way you use the bathroom

Before choosing tile, a shower base, or glass, think about what you want the new space to do. Is the goal easier entry? More room to move? A cleaner, simpler look? Better storage? Your answers shape practical decisions, including the shower footprint, entry style, fixtures, and shelving.

A tub alcove can often provide a natural footprint for a shower, but that doesn’t mean every existing component will work as-is. The drain, floor structure, wall condition, and plumbing may need attention once the tub and surround are removed. A walkthrough and careful measurements help establish what the space can accommodate before materials are ordered.

Also consider how the new shower will fit into the rest of the room. A sliding glass door, for example, needs a different clearance than a hinged door. Built-in niches can keep everyday products within reach, while a bench or blocking for future grab bars may support changing accessibility needs. It’s easier to plan these features early than to retrofit them later.

Decide what kind of shower system fits

Homeowners typically choose between a prefabricated shower system and a site-built shower finished with tile or other wall materials. Each can be a good solution, depending on your priorities, bathroom layout, and project scope.

A prefabricated system can offer a streamlined appearance and integrated shelves. A site-built shower allows for more flexibility in finishes, dimensions, and details. The right choice depends on how you want the shower to look and function, as well as what the existing room and project budget can support.

Whichever system you consider, ask how the shower base, walls, seams, corners, and plumbing penetrations will be waterproofed. The parts need to work together as a complete assembly. Tile and grout may form the visible finish, but they should not be treated as the waterproofing system on their own.

Don’t assume the old tub plumbing can stay

The plumbing is one of the most important parts of a tub-to-shower conversion. The shower may require adjustments to the drain, trap, supply lines, or valve. The existing drain may not be appropriate for the planned shower, and moving its location can involve work beneath the floor.

Before construction, your contractor should assess what’s in place and explain any necessary changes. It’s also worth choosing the valve, trim, showerhead, and handheld features early. These decisions can affect the rough-in. The stage when pipes and components are installed before the walls are closed.

Ask how the proposed layout accounts for:

• The shower drain location and connection

• The shower valve and fixture placement

• Any required access to plumbing

• The floor and subfloor condition

• The selected shower base and wall system

A low estimate that leaves these details unclear may not represent the full project. A thorough proposal should help you understand what’s included and how the contractor will address conditions discovered during demolition.

Treat waterproofing as essential, not an upgrade

Water can cause damage long before a problem is visible in the bathroom. A durable conversion needs a properly installed shower base and a compatible waterproofing approach for walls, corners, joints, and penetrations.

The details depend on the system selected. The contractor should follow the product’s installation instructions and applicable code requirements, and should be able to explain how transitions and openings will be sealed. Ask how the shower will be checked before it is covered, and whether the project requires an inspection at that stage.

The City of Columbus provides specific guidance for site-fabricated showers, including inspection considerations for the shower base and liner. Its site-fabricated shower communication explains why the waterproofing work needs to be inspected at the right point, not after it has disappeared behind finished walls.

Check permits before work begins

Permit requirements depend on the project scope and the jurisdiction where your home is located. In Columbus, the city’s Typical Residential Projects guide lists a kitchen or bath remodel as requiring a permit and plan review. Plumbing or electrical work may have separate permit requirements.

If your home is elsewhere in Greater Columbus, confirm the requirements with the authority that serves your address. Don’t rely on an assumption that the rules are identical from one community to another. Your contractor should discuss permits and inspections with you before the work starts and explain how they fit into the project schedule.

For Columbus-specific questions, contact Building and Zoning Services. Getting clarity at the outset helps avoid delays and makes sure important work is handled in the correct order.

Look beyond the lowest estimate

When comparing proposals, don’t focus on the final number alone. Ask what each estimate includes: demolition, disposal, plumbing changes, the shower base, waterproofing, wall finishes, fixtures, glass, and any repairs to the floor or framing.

A significantly lower price may reflect a narrower scope, different materials, or details that haven’t been confirmed. That doesn’t automatically make a bid wrong, but it does make a careful comparison important. Ask contractors to clarify exclusions, allowances, how changes are approved, and what happens if demolition reveals water damage or another hidden issue.

Good communication matters just as much as the materials. You should know who to contact, when you’ll receive updates, what decisions are still needed, and when the bathroom may be unavailable. A clear process makes it easier to plan around the work and address questions promptly.

Plan the conversion in a sensible sequence

A well-organized project generally follows a sequence: confirm the design and scope, check permits, order materials, protect the work area, remove the tub and surrounding materials, inspect what’s behind them, complete necessary repairs and rough plumbing, and install the shower system. Required inspections should happen before concealed work is covered. Finishing work (such as wall surfaces, fixtures, and glass) follows.

The exact schedule depends on the bathroom, selected materials, and any concealed conditions. Ask your contractor to explain the anticipated stages and flag decisions or deliveries that could affect timing. Documenting the existing bathroom and confirming details before demolition can help reduce avoidable surprises.

Get a shower designed around your home

A tub-to-shower conversion is a chance to improve how your bathroom works, not simply replace one fixture with another. Good planning connects the layout, plumbing, waterproofing, finishes, and project communication from the start.
