Because the 1970s is the biggest single decade in Lenexa's housing stock, the first thing worth establishing on a bathroom here is which side of about 1980 the house falls on. In the 1970s houses the supply branches are often galvanized, the tub is frequently steel or cast iron in a tiled alcove, and the subfloor is first-generation particleboard that has been living under sheet vinyl for fifty years. In the 1990s houses it is copper, a one-piece fiberglass unit and a much shorter list of unknowns. Those are two different bids. We scope a Lenexa bathroom with the supply line and the subfloor called out as separate decision points on the older stock, because in that cohort they genuinely are the variables rather than the finishes.
What the work covers
- Demolition to the studs and subfloor wherever the existing waterproofing is suspect
- Supply and drain rework, including moving the toilet flange or shower drain if the layout changes
- Shower pan and wall waterproofing as one bonded system, not a patchwork of products
- Backing and blocking for grab bars, benches, glass and wall-hung fixtures
- Exhaust ventilation ducted to the exterior, never into an attic or soffit
What we find in Lenexa homes
- Galvanized supply branches in the 1970s cohort that makes up the largest share of this city's housing.
- Steel or cast iron tubs set in tiled alcoves over a mortar bed, which changes demolition weight and debris handling.
- First-generation particleboard subfloor under sheet vinyl, concentrated at the flange and the tub apron.
- A City of Lenexa business license required for the plumber and the electrician, not just the general contractor.
Working in Lenexa, KS
Lenexa has roughly 25,600 housing units and a median year built of 1991, but the median hides the detail that matters most on a jobsite here: the single largest cohort is the 1970s, at about twenty-two percent of the stock. That puts a large share of Lenexa houses at exactly the age where original wiring, galvanized supply lines and first-generation subfloors stop being background detail and start setting the scope of a remodel. A 1970s house and a 1990s house in this city need two different conversations, and the address decides which one.
Permits and inspections run through the Community Development Department's Licensing and Permitting division, filed on Accela Citizen Access. Lenexa is one of the few Johnson County cities that stacks its own business license on top of the county contractor license, and it applies that requirement to every subcontractor rather than to the general contractor alone, which is why the credential check here happens before trades are scheduled instead of after. The trade qualification itself is the Johnson County Contractor License, and MrImproveIt holds Class C residential. The code package is its own combination: the 2018 International Residential Code, adopted by Ordinance 5696 and implemented April 1, 2019 then updated by Ordinance 5890 effective August 1, 2022, alongside the 2017 National Electrical Code and a still-in-force 2012 International Energy Conservation Code. Neighborhoods we work in include Old Town Lenexa, Falcon Valley, Canyon Creek, Four Colonies, Greystone Estates and Timber Rock.
How this job goes wrong
- Waterproofing treated as a product instead of a system, so the pan, curb and wall planes are never actually tied together
- An exhaust fan venting into the attic, which relocates the moisture problem rather than solving it
- Tile set on a floor that was never flattened, which telegraphs lippage across large-format tile
Planning range
$14,000 to $45,000. A tub-in-place refresh sits near the bottom. A gut to the studs with moved plumbing, custom glass and large-format tile sits at the top or past it. Plan on two to five weeks of active work once materials are on site.
What moves the price on a bathroom remodel in Lenexa
A Lenexa bathroom prices first on the age of the house, because that decides whether the supply lines and the subfloor are variables or knowns. In the 1970s cohort, which is the largest in the city, galvanized branches and particleboard underlayment are both realistic findings and both are written as identified lines rather than absorbed into a lump sum. In the 1990s cohort neither is usually in play. After that the drivers are whether the drain stays put and what the tile pattern costs in labor. The Lenexa-specific line is scheduling rather than materials: every sub on the job needs a City of Lenexa business license as well as the county trade license, so the trades are confirmed credentialed before they are booked.
Permits and inspections for this work in Lenexa
Lenexa takes residential permit applications and schedules inspections through Accela Citizen Access, with the Licensing and Permitting division of Community Development handling both the contractor credential side and the permit side. That pairing is deliberate here, because Lenexa requires a City of Lenexa Business License in addition to the Johnson County contractor license and applies it to every subcontractor on the job, not just the general contractor. Work is reviewed against the 2018 IRC, adopted by Ordinance 5696 and implemented April 1, 2019 then updated by Ordinance 5890 effective August 1, 2022, with the 2017 NEC covering circuit work. We confirm which amendment package applies and verify every sub's credentials with the division before the trades are scheduled.
Common questions about this work
Does a bathroom remodel in Lenexa need a permit?
Usually yes, as soon as plumbing, electrical or framing changes. Permit requirements are confirmed with the local building department before work starts.
Can the bathroom stay usable during the work?
Not that bathroom. If it is the only full bath in the house, that changes the schedule, and it is worth saying so before the estimate is written.
How long is the bathroom out of service?
Plan on two to five weeks of active work once materials are on site. Tile and glass are the long poles, because glass is measured only after tile is set.
Bathroom Remodeling questions from Lenexa homeowners
Why does Lenexa care which subcontractor is on my bathroom?
Because Lenexa requires a City of Lenexa Business License for the general contractor and for every subcontractor working in the city, on top of the Johnson County contractor license that covers trade qualification. A crew that is fully licensed for a job in a neighboring city can still be short a credential here, so the check happens before the trades are booked rather than the morning they arrive.
Does the age of my house really change the bathroom estimate that much?
In this city, yes. The 1970s is the single largest building decade in Lenexa, and that cohort commonly carries galvanized supply branches, a steel or cast iron tub in a mortar-set tile alcove, and first-generation particleboard subfloor. The 1990s cohort has copper, a fiberglass unit and far fewer unknowns. We write the older-stock bids with those items identified rather than absorbed.
Which codes is the work inspected against?
The 2018 International Residential Code, adopted by Ordinance 5696 and implemented April 2019 then updated by Ordinance 5890 in August 2022, with the 2017 National Electrical Code for circuit work. Because the adoption came in two steps, which amendment package applies gets confirmed at plan review rather than assumed.
