Walk-in and curbless shower plumbing in Grand Rapids
Quick answer: Walk-in shower plumbing in Grand Rapids usually costs $1,500 to $4,500. A curbless shower is at the high end because the floor must be recessed so water slopes to the drain. Linear drains, extra body sprays and rain heads all add cost.
What is a walk-in shower?
A walk-in shower is a shower with no tub, and usually no door you have to step over. A curbless shower goes further. It has no curb at all, so the bathroom floor flows straight into the shower. Both need the floor to slope toward a drain, usually a quarter inch per foot.
Point drain or linear drain?
| Center point drain | Linear drain | |
|---|---|---|
| Floor slope | Four ways to the center | One way to the edge |
| Tile size | Smaller tiles work best | Large tiles work well |
| Curbless-friendly | Harder | Easier |
| Typical plumbing cost | Lower | Higher |
A linear drain costs more to buy and install. It’s often worth it for a curbless shower.
Why are curbless showers harder?
A curbless shower must be recessed. The shower floor sits lower than the bathroom floor so it can slope to the drain. That usually means one of these:
- Lowering the subfloor between joists, which may need a carpenter.
- Building up the rest of the bathroom floor.
- On a slab, cutting the concrete to set the drain lower.
Plan this before demo. In many Grand Rapids homes, an open basement ceiling below makes the drain work far easier.
Do multiple shower heads need more plumbing?
Yes. Rain heads, handheld wands and body sprays each need water. A single valve can feed two outlets with a diverter. More than that usually needs a larger valve and bigger supply lines.
Check your water heater too. Two heads at 2.5 gallons per minute each use 5 gallons a minute of mixed water. That can empty a small tank fast. The EPA WaterSense showerhead page lists efficient models.
What does it cost?

These are planning ranges, not quotes. Carpentry, waterproofing, tile and glass are extra.

Common questions
What is a linear drain?
A linear drain is a long, narrow drain that runs along one edge of the shower, often at the back wall or the entry. The floor slopes one way toward it instead of toward a center drain. That lets you use large-format tiles, and it makes a curbless entry much easier to build. Linear drains cost more than standard center drains.
Is a curbless shower good for aging in place?
Yes. A curbless shower has no step to trip over, and it works with a shower chair, walker or wheelchair. Pair it with a handheld showerhead, grab bars on blocking set during framing and a slip-resistant floor. Planning those details during the remodel costs far less than adding them later, and it’s one of the most useful accessibility upgrades.
How low-flow does a showerhead have to be?
Federal rules cap showerheads at 2.5 gallons per minute. WaterSense-labeled showerheads use 2.0 gallons per minute or less and still have to pass a spray test. The EPA says showering is nearly 17 percent of indoor water use. If you add body sprays or a rain head, check that your water heater can keep up.
