Tub-to-Shower Conversion in Bismarck, ND: What to Know Before You Start
If you’ve been staring at a bathtub you haven’t used in years, you’re not alone. It’s one of the most common things we hear from Bismarck homeowners: the tub takes up half the bathroom, nobody uses it, and every time they see it they wish it were a real shower.
A tub-to-shower conversion fixes that — and in most Bismarck homes, we complete the entire project in three to five days.
This guide walks you through what the process actually looks like in a Bismarck home, what affects the cost, what material choices make sense for our water supply, and how to know if you’re ready to move forward.

Why Bismarck Homeowners Convert Tubs to Showers
The reasons vary but tend to fall into three categories.
The tub just doesn’t get used. If everyone in your household showers, a full-size bathtub is essentially a very expensive floor space holder. Converting it to a walk-in shower gives that square footage back to you in a way you’ll actually use every single day.
Aging in place and accessibility. Stepping over a tub wall becomes riskier as we get older. A low-threshold or curbless walk-in shower eliminates that barrier completely. Many Bismarck homeowners make this upgrade for themselves or for an aging parent moving in — and they always wish they’d done it sooner.
The bathroom just needs a refresh. Bismarck homes — especially those built in the 1970s through 1990s — often have original tub-shower combos that show their age. Discoloration, grout that won’t stay clean, caulk that keeps cracking. A conversion is an opportunity to start completely fresh with materials built for longevity.
What the Process Looks Like in a Bismarck Home
Every conversion starts the same way: a free in-home consultation at your Bismarck address where we measure the space, assess the plumbing, and check the subfloor condition. That last part matters more than most people realize.
Subfloor inspection is non-negotiable. Bismarck homes — particularly older ones near the river or in established neighborhoods — sometimes have subfloor damage from years of slow leaks around tub caulk lines. We find it before it becomes your problem after installation. Any damage gets repaired before a single panel goes up.
Drain assessment. Tubs and showers drain differently. Most conversions require a drain adjustment, and we handle that as part of the project so there are no surprises down the road.
Installation day. Once materials are confirmed and the space is prepped, installation typically runs one to three days. We work cleanly, protect your floors, and leave the space spotless when we’re done.
Our 5-year labor warranty covers every conversion we complete in the Bismarck area. The Onyx Collection materials we primarily install carry a lifetime warranty on top of that.
Material Choice: Why Onyx Makes Sense for Bismarck
Bismarck’s water is hard. If you’ve lived here more than a few years, you already know this — you see it on your fixtures, on your glass, and eventually worked deep into your shower grout.
Tile is beautiful but it has grout lines. Grout lines are porous. Bismarck’s mineral-heavy water bonds into those lines over time and no amount of scrubbing gets it fully out. Fiberglass and acrylic surfaces scratch, dull, and eventually stain in ways that can’t be reversed.
We primarily install The Onyx Collection for Bismarck conversions because its non-porous solid surface has no grout lines at all. Minerals can’t penetrate it. Mold has nowhere to grow. Cleaning is a single wipe-down. It comes in over 60 colors and patterns, is custom-fabricated to your exact dimensions, and carries a lifetime warranty.
It’s not the cheapest option on the market. It’s the right option for this climate and this water supply — and the homeowners who choose it never regret it.
What Does a Tub-to-Shower Conversion Cost in Bismarck?
Most conversions in the Bismarck area fall between $3,500 and $12,000 depending on three main factors: the size of the space, the materials you choose, and whether any plumbing or subfloor work is needed.
An Onyx Collection conversion in a standard Bismarck tub footprint typically runs $5,500 to $8,500 — that includes custom panels, a fitted Onyx base, drain upgrade, and all labor.
The only way to get an accurate number for your specific bathroom is the free in-home consultation. We look at your space, your existing plumbing, and your subfloor — and give you a detailed written estimate on the spot.

Common Questions from Bismarck Homeowners
Will removing my tub hurt my home’s resale value? Not if you have at least one other tub in the home. A high-quality walk-in shower in a multi-bathroom Bismarck home typically holds or increases value — many buyers, particularly those without young children, actively prefer it. If your home has only one bathroom, it’s a conversation worth having during your consultation.
Do I need to move out during the conversion? In almost all cases, no. We work in a contained area and most Bismarck homeowners with a second bathroom are comfortable throughout. We’ll give you a realistic picture during your consultation based on your specific layout.
How long will it take? Three to five days for a standard Bismarck conversion. Complex projects with significant subfloor repair or custom plumbing work may run slightly longer — we’ll tell you upfront.
Do you handle the plumbing? We coordinate with licensed plumbers for any required plumbing work. We manage the process so you’re not dealing with multiple contractors.
Can I see Onyx samples before I decide? Yes — our Bismarck showroom at 815 E Main Ave has Onyx Collection samples you can see and touch in person. Monday through Friday, 8am–5pm.
Is a Tub-to-Shower Conversion Right for You?
It’s the right move if you have a tub you’re not using, you want a shower that’s easier to clean and better suited to Bismarck’s water, or you’re thinking ahead about accessibility and safety.
It’s worth a conversation first if you have only one bathroom or if you have young children who still rely on a tub regularly — not a dealbreaker, just something to factor into the decision.
Either way, the free consultation costs nothing and leaves you with a written estimate and a clear picture of your options. No pressure, no obligation.
