Tub-to-Shower Conversion Cost in Columbus: Like-for-Like vs Tiled

A like-for-like tub-to-shower swap in Columbus runs about $8,800 to $11,400 in a standard 8-by-8 bathroom and takes roughly a week. Tile the same room instead of paneling it and the range moves to $17,900 to $24,200 over two to three weeks. The shower is not what separates them. Forty hours of tile work, a waterproofing assembly and a full gut are.

What does a tub-to-shower conversion cost in Columbus?

There are two versions of this job and they are priced from different tiers of the estimator on this site. The like-for-like version replaces the tub with a prefabricated shower base and a panel or insert surround, leaves the drain and the valve where they are, and refreshes the rest of the room. That is the standard tier. The tiled version guts the room, rebuilds the wet wall with backerboard and a waterproof membrane, tiles the surround and the floor, and sets a new fan and light. That is the mid-range tier.

Neither column includes permit fees, mold or asbestos remediation, a panel upgrade, or relocating a main waste or supply riser.

What does the like-for-like swap actually include?

The standard tier keeps the layout. The tub comes out, a prefabricated base goes in where the tub sat, and the surround is a panel or insert system rather than tile. The plumber replaces the fixtures in their existing locations, which is a same-day sub visit rather than a rough-in. Electrical is limited to GFCI receptacles and a new light. The floor gets luxury vinyl plank or sheet vinyl, the vanity and mirror are replaced, baseboard is reset, and the room gets two coats of paint.

Seventy-two man-hours at standard size is the whole job: 16 for demo, 8 for framing and subfloor patching, 8 for electrical, 12 for drywall, 16 for finish work, 8 for paint and 4 for cleanup. There is no tile line at all, which is the single reason the total is roughly half of the tiled version.

What the standard tier does not buy is worth stating plainly: no new layout, no tiled surround, no second sink, no recessed niche, and no frameless glass. It also leaves the exhaust fan alone unless the existing one has failed. If the room has no fan and no operable window, that changes the electrical scope and the tier along with it.

The surround is the real trade-off. A panel system is a finished, waterproof product, but it is a manufactured look and the seams are visible if you look for them. It is also the right answer for a rental, a secondary bath, or a house going on the market.

What does the tiled version add?

Five things, and they compound.

Forty man-hours of tile. At the $85 rate the estimator uses, that is about $3,400 of labor at standard size before a single tile is purchased. Scale it by room: 1.2 for an 8-by-10 bath, 1.5 for a 10-by-12.

A waterproofing assembly. Half-inch backerboard and a waterproof membrane go on before the tile. This is not optional and it is not the same as greenboard. The tile has to sit on a surface rated for it, which is the rule that most often separates a shower that lasts twenty years from one that fails at the corner in five.

A full gut. Demo goes from 16 to 24 man-hours because the wall covering comes off as well as the fixtures, and the scope adds floor-to-ceiling dust containment and a dumpster.

A real electrical scope. Mid-range adds a new 20-amp GFCI circuit and both a vanity light and a ceiling fixture, against the standard tier's single replacement light. Eight electrical man-hours cover it at either tier, but the circuit itself is new work and it is one of the triggers for a permit.

More cure time than work time. Floor tile, surround tile and grout are three separate operations, each waiting on the one before it. That is why nine crew days of labor take two to three calendar weeks to finish.

If the tiled version is what you want but the shower is also moving or changing shape, the job crosses into high-end territory. That case is priced separately in walk-in shower conversion cost.

What does a one-week bath cost in Columbus?

About $8,800 to $11,400 for a standard 8-by-8 room, and $7,110 to $9,288 for a small 5-by-8. A week is what a like-for-like swap takes when nothing moves: 72 man-hours is about 4.5 crew days at 16 man-hours a day, plus a plumber visit and the time finishes take to arrive.

A one-week bath assumes four things stay true. The drain and the valve stay where they are. The surround is a panel or insert system, not tile. Nothing structural is found behind the tub. And the fixtures are on site before demo starts, because the schedule has no slack in it.

Break any one of those and the week becomes two. The most common breakage in central Ohio is what is behind the wall: pre-1960 inner-ring houses turn up galvanized drain lines that have to be replaced once they are opened, plaster instead of drywall, and mortar-bed tile that takes twice as long to remove. Houses from the 1980s through the 2000s are easier, but the coated steel tub and the particleboard vanity are usually both at the end of their lives.

What moves the number?

Room size. The estimator scales the entire job by floor area: 0.75 for a 5-by-8 bath, 1.0 for 8-by-8, 1.2 for 8-by-10 and 1.5 for a 10-by-12 primary bath. The side-by-side comparison for every tier is in primary bathroom versus hall bathroom remodel cost.

Site difficulty. A flat multiplier on labor, subcontracts and materials. A second-floor bathroom adds 5 percent, a tight hallway 10, an occupied home 20, a basement bathroom 30. On the standard tier base range of $8,120 to $9,744, the 5 percent step is $406 to $487 and the 30 percent step is $2,436 to $2,923.

Whether the plumbing moves. A shower base rarely lines up perfectly with a tub drain, and the further the new drain sits from the old trap arm, the more floor or ceiling has to come open. The same arithmetic governs every fixture, which is why moving the toilet is the most expensive small decision in the room.

The door. The standard tier allowance of $30 to $50 is a curtain rod. Mid-range allows $50 to $1,000, which covers a sliding or framed hinged door. Frameless glass belongs to the tiers above.

The bathroom cost estimator lets you set the tier, the size and the difficulty and see the effect of each one in turn.

Does a tub-to-shower conversion need a permit in Columbus?

A like-for-like swap that replaces fixtures in their existing locations generally does not. The Columbus Department of Building and Zoning Services requires a permit when plumbing or electrical is moved or added or when framing is altered, so a swap that relocates the drain, adds a circuit or opens a wall does need one.

The Ohio Plumbing Code sets a minimum size for the shower receptor, which matters when a 60-inch tub alcove is filled by a base that leaves less usable floor than it looks like on paper. Check the finished opening and the swing of the door against the figures in the notes on NKBA bathroom clearances before anything is ordered.

Which version fits the bathroom you have?

Choose the like-for-like swap when the bathroom is a secondary or hall bath, the layout works, the budget is the constraint, and a week without that bathroom is the most you can absorb. It is the highest-value version of this job per dollar spent.

Choose the tiled version when the bathroom is the one you use every day, when the surround is going to be looked at for the next fifteen years, or when the wall is already opening for another reason. Once a wall is open and a dumpster is on the drive, the incremental cost of tiling is labor you will not pay a second time.

What to do next

Price both. The gap between the two columns in the table above is the actual decision, and it is larger than most homeowners expect: roughly double at every room size.
