A tub-to-shower conversion in an Olathe house is usually a straightforward swap inside sound late-century construction, and the local complication is administrative rather than structural. Plumbing is its own permit type in Olathe, not a line inside the building permit, and the licensed plumber has to be verified active in the county system and named individually as permittee. That is a different filing from the one a neighboring city would take for identical work. On the construction side the pattern is consistent: a fiberglass or acrylic unit set against bare studs, a tub waste and overflow where a shower pan does not want its drain, and an alcove with no finished surface behind the unit once it comes out.
What the work covers
- Removing the tub and the surround, which usually means opening the wet wall
- Re-piping the drain, including relocating and resizing the trap for a shower
- Building the pan, either a pre-formed base or a sloped mortar bed with a bonded membrane
- Waterproofing the curb, the corners and the wall planes as one continuous system
- Blocking for a bench, a niche, grab bars and the glass
What we find in Olathe homes
- A plumbing permit filed on its own track, with the licensed plumber verified active and named as permittee.
- A one-piece fiberglass or acrylic unit installed against bare studs before the drywall.
- A tub waste and overflow drain positioned for a tub rather than for a shower pan.
- Framing dimensioned to the original unit, which a replacement pan and wall system rarely matches.
Working in Olathe, KS
Olathe is the Johnson County seat and it runs its own building department rather than going through the county for permits or inspections. The housing stock is younger than the inner-ring suburbs and that sets the tone for the work: of roughly 53,543 units, about 32,531 of them, 60.8 percent, were built between 1980 and 2009, and only 1,509 predate 1950. The genuinely old housing is concentrated in a small area around Original Town and Downtown Olathe. Everywhere else, a remodel here is working inside late-century subdivision construction, where the assemblies are consistent and the surprises are about service life rather than about what century the framing came from.
Permits are issued by the Building Codes Division out of 100 E. Santa Fe Street and filed through the city's Tyler EnerGov self-service portal with the required documents attached. Olathe keeps mechanical, electrical and plumbing as their own permit types instead of rolling them into the building permit, and each Johnson County-licensed contractor has to be verified active and listed by individual name as a permittee. MrImproveIt holds the Johnson County Class C residential license that OMC 15.02.130 requires; Olathe does not add a city contractor license on top of it. Residential plan review runs five business days, and a residential application needing only Building Codes review can run as an Express Permit reviewed in one business day at no extra charge. The code is the 2018 IRC, adopted by Ordinance 19-28 effective September 1, 2019, with the 2017 National Electrical Code.
How this job goes wrong
- A shower run on the old tub drain and trap, which drains slowly and is not compliant
- A pan sloped the wrong way, or a membrane that stops short of the curb
- A curbless entry attempted without lowering the framing, so the slope has nowhere to go
Planning range
$9,000 to $26,000. A solid-surface base in the existing footprint with a standard framed door sits near the bottom. A tiled curbless pan with frameless glass and an accessibility package sits at the top. Plan on one to three weeks of active work.
What moves the price on a tub to shower conversion in Olathe
A conversion here prices on whether the drain moves, whether the alcove needs reframing, and what the wall system is, with the Olathe wrinkle that the plumbing carries its own permit and its own named permittee rather than sitting inside a building permit. Keeping the existing drain location is the cheapest version of this job in any city and it matters a little more here, because it keeps the plumbing filing narrow. Tile is a labor number; a solid-surface or acrylic wall system is a material number with a shorter schedule. Work is reviewed against the 2018 IRC, which Olathe adopted by Ordinance 19-28 effective September 1, 2019.
Permits and inspections for this work in Olathe
In Olathe the plumbing work on a conversion is its own permit type rather than a component of the building permit, filed through EnerGov by the licensed plumber, who has to be verified active in the Johnson County system and listed by individual name as permittee. That is the main administrative difference from an identical job in a neighboring city. Review is against the 2018 IRC adopted by Ordinance 19-28, with the 2017 NEC covering any circuit work. Residential review is five business days and the permit stays active 180 days from issue. We verify the current submittal requirements with the Building Codes Division rather than working from a previous job's checklist.
Common questions about this work
Is a tub to shower conversion a permit job in Olathe?
It changes the drain and usually the valve, so it generally is. Permit requirements are confirmed with the local building department before work starts.
Should I keep one tub in the house?
Worth considering at resale, particularly if this is the only one. If another full bath has a tub, the concern mostly goes away.
Can the shower be curbless?
Sometimes, and the answer depends on the floor framing below. It has to be decided before demolition, because it is a framing change rather than a finish change.
Tub to Shower Conversion questions from Olathe homeowners
Does a conversion need its own plumbing permit in Olathe?
Yes. Plumbing is a separate permit type here rather than part of the building permit, and the licensed plumber must be verified active in the Johnson County system and listed by individual name as the permittee. It is a different filing from what a neighboring city would take for identical work.
How long is an Olathe permit good for?
An issued permit stays active 180 days. Residential plan review runs five business days, and an application that only needs Building Codes review can run as an Express Permit reviewed in one business day at no extra charge, which suits a single-room scope like this one.
Will the shower drain end up where the tub drain was?
Not usually. The original unit used a tub waste and overflow, which sits in a different place than a shower pan wants. If a pan can be selected around the existing drain the floor stays closed and the plumbing filing stays narrow. That is the first thing checked on site because it sets the rest of the number.
