Rapid Valley Tub to Shower Conversions
Builders put a standard 60-inch tub in these ranches because it was the cheapest way to close a bathroom, and thousands of them out here have never held water. Bruce pulls the alcove, resets the drain where a shower needs it, and hands the room back working, usually on the third day.
THE BUILDER-GRADE ALCOVE
The Tub Your Builder Picked, and Why It Has to Go
Walk into almost any three-bedroom ranch off Highway 44 and the hall bath tells you the same story. Steel or thin acrylic tub, three-piece surround glued to the studs, a soap dish molded into the wall that nobody has ever used, and a sliding door track packed with twenty years of scale. None of it was chosen. It was the package the subdivision bought by the truckload while these streets were filling in, and it has been quietly failing ever since.
Owners rarely call us because the tub broke. They call because the surround has separated at the corner, or because stepping over a fourteen-inch wall each morning stopped being casual. Trading it for a shower you step into, with a curb low enough to clear without thinking about it, changes how the room gets used from the first morning.
Bruce will also tell you when to leave it alone, and he means it. If yours is a two-bath home and both baths still hold tubs, converting the hall bath is easy math. If the house has exactly one tub and the family has small kids, or you expect to sell inside a few years, that tub is worth more where it stands than the shower would be. He would rather write a smaller job and be right about it than talk somebody out of the only tub under their roof.
WHAT THE TEAR-OUT SHOWS
What We Find Once the Surround Comes Off
A Wet Corner Nobody Saw
Peel the surround off and the story is written on the studs. The panel seam behind the faucet is where these units let go first, and water that got past it has been wicking into the bottom plate a drop at a time. On homes from the seventies and eighties we routinely find framing gone punky at the base. It comes out, gets sistered or replaced, and the room gets built back on wood that is actually sound.
Original Plumbing at the End of Its Run
Behind that same wall sits whatever the original crew installed. Sometimes it is fine. Sometimes it is a two-handle valve nobody makes parts for anymore, or supply lines with enough mineral buildup that flow is measurably down. This is the one moment when that wall is open and reaching it costs almost nothing extra, so we deal with it now rather than cutting the same tile back open in four years.
Framing Built Around a Tub
Alcove tubs sit on a ledger and a bed of whatever the installer had handy, boxed in by framing that exists purely to hold a tub in place. Breaking that out is the loud hour of day one, dust and all. What we get for it is an honest look at the joists and a clean, level cavity to build the new base into, instead of shimming a pan over somebody else’s improvising.
DRAIN AND VALVE
Moving the Drain and Setting the New Valve
This is the part of the job that decides everything else. A tub drains from one end, tucked against the wall. A shower base drains from a point the floor slopes toward on all four sides, which almost never lines up with where the tub trap sits. So the drain moves, usually a foot, sometimes closer to two, and getting it right is the difference between a base that sheds water and one that holds a puddle by the far corner.
Most Rapid Valley homes make this straightforward. The ranch and split-level stock through here was built with basements, so we open the bay from underneath, set a new trap at the correct height, run the pitch back into the existing line, and never disturb the finished floor. Homes on slab exist out here too, mostly in the newer construction along the eastern edge, and those need the concrete cut, the line rerouted, and the patch cured before a base goes down. That is a full extra day and it belongs in the written price on day one.
The valve moves with it. Tub-and-shower valves sit low, around knee height, because they have to feed a spout. A shower-only valve belongs up where you can reach it without leaning into the spray, and it needs to be a pressure-balanced or thermostatic unit so a toilet flushing down the hall does not turn the water scalding. We block the wall solid behind the valve and behind both grab bar heights while the studs are exposed, whether or not bars go in this year.
WATERPROOFING, ENTRY, AND GLASS
The Threshold, the Membrane, and What Goes on the Glass
Waterproofing is invisible work, which is exactly why it gets skipped by people racing to a finish price. Whatever goes on the walls, the layer underneath has to be continuous: membrane over the backer, corners and seams banded, the drain flange bonded into the same system, then a flood test before a single tile or panel is set. Skip that step and the failure shows up years later as a soft spot in the hall floor.
On the entry, we build the curb as low as the drain depth and the framing honestly allow. Four inches is common in a basement home. Fully curbless is possible when the joists let us drop the base flush, and it is worth asking about early because it changes the framing plan. Either way the goal is the same: a threshold nobody has to think about, at forty or at eighty.
South Dakota water settles the glass question faster than any showroom conversation. The mineral load out here is real, and untreated glass shows every drop of it. We steer most Rapid Valley households toward a treated clear panel with a hinged door, or a single fixed panel with an open entry and no door at all. Framed sliders are cheaper and we will install one, but the bottom track collects the same scale the old tub door did.
SCOPE AND SCHEDULE
Two to Three Days, and What Each One Covers
- Walkthrough and a written line-itemed price
- Tub, surround, door track, and framing removed
- Debris hauled off, nothing left in your driveway
- Framing and subfloor repaired where water got in
- Drain relocated and pitched for the new base
- Supply lines replaced where they are shot
- Pressure-balanced or thermostatic valve set
- Membrane waterproofing and a flood test
- Base, walls, niche, and low-threshold curb
- Glass panel or door, trim, sealant, hardware
- In-wall blocking at both grab bar heights
- County permit pulled when the scope calls for one
Day one is demolition and rough plumbing. Day two is waterproofing, the base, and walls. Day three is glass, trim, sealant, and cleanup, and that is when you get the room back. A tile build runs longer, closer to a week, because grout and sealant will not be hurried.
The toilet and sink stay live except during the plumbing hours on day one, and the crew is out of the house by supper. If this is the only bathroom you have, say so on the walkthrough, and we will tell you plainly which night the shower is offline instead of letting you find out.

QUESTIONS WE GET ASKED
Rapid Valley Tub to Shower Conversion Questions
How many days will my bathroom be torn apart?
Two to three days for an acrylic or solid-surface conversion, about a week for tile, plus a day if the drain has to come through a slab.
We only have one tub. Should we keep it?
Usually yes, and Bruce will say so at the walkthrough. With young kids at home or a sale coming inside a few years, the last tub earns its space. Put the money into the rest of the room instead and convert once a second bath exists.
Do we need a permit out here?
Because these addresses sit outside Rapid City limits, the paperwork goes to the county building office, and a conversion that relocates the drain will need one. Bruce holds the South Dakota general contractor license, files it himself, and meets the inspector on site.
Can the shower end up larger than the tub was?
Sometimes. If the wall behind the tub is a partition with a linen closet on the far side, borrowing a foot buys you a bench and room to turn. If it carries load from above, we keep the footprint and design a better shower inside it.
Will hard water ruin the new glass?
Not ruin it, but untreated glass will spot fast around here. A factory-treated panel wipes down in seconds and stays clear for years. An open walk-in entry with one fixed panel and no door is the lowest-maintenance option we install.
Does this work in a manufactured home?
Yes, and Rapid Valley has several manufactured home communities where we have done it. The framing, floor structure, and plumbing runs differ from stick-built, so the base and wall system get selected for that. Mention the home type when you call.
WHERE WE WORK
Fifteen Minutes From the Shop
Our shop sits in Rapid City, roughly fifteen to twenty minutes from most Rapid Valley addresses. That closeness is practical, not marketing: Bruce can swing by after work to look at your alcove, and if a part is needed mid-job nobody loses a day driving for it. Elk Vale Road, the Highway 44 corridor, and the newer streets on the east side are all inside that easy range. See finished showers in the project gallery, then tell us about your bathroom and we will get on the calendar.
Ready to Lose That Tub?
Bruce Miller comes out, measures the alcove, checks what is under the floor, and writes the number down before anybody commits to anything. Veteran owned, fifty years in the trade, and a straight answer about whether your house should keep its tub.
