How to Build a Shower
The Complete Buying Guide
A shower is the fixture you use every single day, and the one with the most moving parts to get right. Unlike a toilet or a tub, you don't buy a shower in one box — you assemble it from a base, a door or enclosure, a shower head and valve, and the drains and storage that finish it. This guide walks through those choices in the order that matters, so every piece fits your space, works together, and shares one clean finish.
Measure your space and pick a configuration — walk-in or tub-to-shower. Choose a base that fits (or plan a tiled pan), then a door or enclosure in the right size and installation type. Pick a shower head — fixed, handheld, rain, or a combination of all three — and the proper valve configuration behind it. Add a drain, and a wall niche if desired, to finish. Then choose your hardware finish color and carry it across every piece.

the 6 decisions
Every well-built shower answers these questions,
roughly in this order.
- Step 1
What's my space and configuration?
Walk-in or tub-to-shower; alcove, corner, or neo-angle.
- Step 2
What base sits on the floor?
A ready-made base or a tiled pan — size, shape, and threshold.
- Step 3
What door or enclosure?
Installation type, glass, and size.
- Step 4
What shower head and valve?
Fixed, handheld, rain, or a combination of all three — plus the valve behind the wall.
- Step 5
What drainage and storage?
Drain style and the sizing of a wall niche.
- Step 6
What is your desired finish?
Brushed nickel, matte black, brushed gold, or chrome.
Measure your space and
choose a configuration
Start with the footprint you have and how you want to use it. This decides everything downstream.

2 configurations
Walk-in or tub-to-shower
A walk-in shower is a dedicated stall — the modern, open, easy-access choice, and the best use of space in a bathroom without a tub. A tub-to-shower conversion replaces an old tub with a shower to reclaim room and step-over ease. If this is your only bathroom, keep at least one tub in the home for resale.
-
3 layouts
Shape and layout
Alcove — set between three walls with a door across the front; the most common and space-efficient layout. Corner — fits into a corner finished with two glass sides, reclaiming an otherwise unused spot. Neo-angle — an angled corner unit with a diagonal door; compact and distinctive.

Measure before you shop
Measure the width, depth, and the exact opening where the door will go — glass doors are sized precisely, so a careful measurement is essential. Note your ceiling height if you want a ceiling-mount rain head, and confirm the door has room to open without hitting the rain head or any fixtures inside the room.
Standard walk-in shower footprints start around 32" x 32" and 36" x 36", with 36" x 48" and larger for a roomier stall. Confirm your base size and door width work together before ordering either one.
Choose your
shower base
The base (or shower pan) is the waterproof floor of the shower. You can tile a custom pan, but a ready-made shower base installs faster, seals reliably, and cleans easily. Swiss Madison offers various types of shower bases and materials, so most layouts have a ready fit.
| BASE | What it is | Best for | Install effort |
|---|---|---|---|
| Standard threshold | A low curb that contains water. | The everyday choice for most showers. | Step-over |
| Low-threshold | A minimal curb for an easier step-in. | More accessible entry with a cleaner profile. | Easy step-in |
| Curbless | No step at all — the floor runs straight into the shower. | A seamless modern look; pairs well with a linear drain. | Level |
| Seated base | A base with a built-in bench, as on Swiss Madison's Aquatique. | Comfort and accessibility. | Seated |
Match the base to your footprint and layout — square bases suit alcoves and corners, while rectangular bases suit longer walk-ins. Confirm the drain position (center or offset, sometimes reversible) lines up with your plumbing before you order.
Choose your door or enclosure
The door defines the look of the shower and keeps water where it belongs. Choose the style, then the glass and finish of your shower door.
| Door style | What it is | Best for | Swing space |
|---|---|---|---|
| Fixed / walk-in panel | A single stationary glass panel with an open walk-in gap — no moving door. | A clean, open, low-maintenance modern look. | |
| Hinged | A door on hinges that swings open like a standard door. | Alcove and corner stalls with room to swing out. | |
| Sliding / bypass | Two panels that slide past each other on a track. | Wider openings and tub-shower combos where a swing won't fit. | |
| Neo-angle | An angled door built for a corner installation. | Corners and compact bathrooms. |
Glass and frame
Thicker glass feels more solid and premium. Swiss Madison shower doors use 3/8-inch (10mm) tempered safety glass across all collections, with clear or frosted glass and a choice of frame finishes. Clear glass shows off your tile and feels open; frosted glass adds privacy.
Framed vs. frameless. Framed doors use a metal frame for structure and value; frameless doors use thicker glass and minimal hardware for a nearly invisible look. Semi-frameless sits in between. Choose by budget and how minimal you want the glass to read.
Choose your shower head and valve
Water flow
Standard shower heads flow at the federal maximum of 2.5 GPM (gallons per minute). For water savings, a WaterSense head at 2.0 GPM or less cuts water and energy use while keeping strong pressure. For further savings or for California residents, a CEC-compliant shower head uses a maximum of 1.8 GPM.
The valve behind the wall
The shower head and handle you see are the trim; the rough-in valve is the part inside the wall that controls water. A pressure-balance valve keeps the temperature steady while other fixtures are consuming water; a thermostatic valve holds an exact set temperature. Choose the trim and valve together, and match the trim finish to the rest of the shower.
Finish family
A shower head fixed to the wall above your shower valve controls.
Choose a rain head for a soft, drenching feel.
Any of the above combined using a 2- or 3-way diverter valve,
so you get more than one spray option.

Order the trim kit and its matching rough-in valve together so they're compatible. Swiss Madison trim kits, like the Ivy series, come in tub, shower, and handheld configurations to match how you'll use the shower. Browse shower heads.
Add drainage
and storage
The finishing details make a shower easy to live with — and are simplest to plan before the walls close up.
Shower drain
Beyond function, a decorative drain is a small design touch you can match to your finish; linear drains suit curbless and modern showers.
Shower niche
A recessed shelf built into the wall keeps bottles off the floor and looks far cleaner than a hanging caddy. Plan its placement and size before tiling — see shower niches.
Bench or seat
A built-in bench or a seated base adds comfort and accessibility.
Choose one finish and coordinate
Because a shower is assembled from separate pieces, the finish is what makes it read as one design. Pick a single finish — Swiss Madison offers Chrome, Brushed Nickel, Matte Black, and Brushed Gold across shower heads, trim, door frames, and drains — and carry it through every part, then out to the faucet, towel bars, and hardware in the rest of the room.
This is exactly where Swiss Madison is built to win: a premium, coordinated look at an attainable price. Because we design our own products and offer them direct and through major retailers, you can build a complete, matching shower — base, door, head, valve, drain, and niche — in one finish and one design language, without overpaying for a luxury name.
Planning the installation
A shower involves waterproofing, glass, and plumbing behind the wall, so most installs are a job for a professional. Whoever does the work, plan these before the walls close:
Set the valve rough-in and confirm pressure-balance vs. thermostatic before tiling — it's very hard to change later.
Waterproof the base and walls properly; the base and pan liner are what keep water out of the structure.
Confirm the base drain lines up with your plumbing, and that the drain style matches your finish.
Frame in the niche and any bench before tile, and slope the niche sill so water drains out.
Measure the finished opening precisely before ordering glass — doors are cut to size.
Order the trim kit and matching valve together, in the same finish as the door and drain.
