Custom Shower Installation

Every Shower Built From the Ground Up

A shower is not a box with tile on it. It is an engineered wet environment that demands precision waterproofing, proper slope, and materials that can handle decades of daily use without failing. At Nautilus Design and Build, every custom shower we install in Whitefish, Kalispell, and the Flathead Valley is built using time-tested construction methods that most modern contractors have abandoned in favor of speed and cost cutting.

Levi Shewalter brings over 22 years of hands-on experience to every shower project. Whether you need a straightforward walk-in shower remodel, a traditional mud-set shower with a hand-floated mortar bed, or a curbless barrier-free shower designed for accessibility and modern luxury, Nautilus has the skill set and the patience to do it right. We do not subcontract our shower work. Levi and his crew handle every phase of the build from demolition through final grout.

The process begins with a thorough assessment of your existing space. We evaluate the subfloor condition, framing, plumbing locations, and drainage requirements before any work starts. For new shower builds, we construct the shower pan from scratch using either a traditional mortar bed or an engineered substrate system, depending on the design. Every surface that will be exposed to water receives full waterproofing membrane coverage. This includes the floor, all walls up to and beyond the showerhead height, the curb, built-in niches, and bench seats.

Tile selection is critical in a shower environment. Nautilus works with porcelain, natural stone, ceramic, and glass tile to create showers that are as beautiful as they are functional. We guide our clients through material choices based on water absorption rates, slip resistance, maintenance requirements, and long-term durability. Small-format mosaics on shower floors provide traction, while large-format tiles on walls reduce grout lines and simplify cleaning.

We also specialize in tub-to-shower conversions, one of the most requested bathroom upgrades in the Flathead Valley. Removing an old bathtub and replacing it with a spacious walk-in shower transforms the entire bathroom, adds usable space, and dramatically modernizes the room. Every conversion includes new plumbing, a custom-built shower pan, full waterproofing, and hand-set tile throughout.

For homeowners looking for something beyond a standard shower, Nautilus builds multi-head shower systems with body sprays and rain heads, steam showers with proper vapor barriers, and large-format wet rooms that blur the line between shower and bathroom. These luxury installations require advanced plumbing knowledge and meticulous waterproofing, and they are where Nautilus truly sets itself apart from general contractors.

Our custom showers are a cornerstone of our full bathroom renovations and pair perfectly with our custom tile installation services. Every shower we build is designed to last, built to perform, and finished to a standard that speaks for itself.
