Shower Selection Guide

Designing your shower system starts with understanding your space, water needs, and lifestyle preferences. This step-by-step guide walks you through each decision — from layout planning to control selection — to help you build the perfect shower experience.

STEP 1: Confirm the Bathroom Layout

Start by identifying the layout of your bathroom. This determines the number of outlets, the type of control system, and the valve configuration.

● Single Shower Area→ One user, standard setup
● Couple Shower Area→ Two users, more capacity and parallel usage
● With Bathtub→ Requires a tub faucet in your system configuration

Your layout affects component count, valve selection, and control method.

STEP 2: Choose Between Normal vs Wellness System

This step determines whether you’ll need a standard or high-capacity valve.

● Normal Solution→ Traditional showering experienceIncludes: standard shower head, hand shower, tub spout
● Wellness Solution→ Spa-level experienceIncludes: multiple body jets, rain showers, multifunction heads, high volume outputRequires high-flow rough-in valves and controls

STEP 3: Select Your System Functionality

Decide how many functions or water outlets you want to control. This will determine the diverter or number of volume controls required.

Function TypeComponentsSystem Implication
2-FunctionE.g., shower head + hand showerBasic diverter or volume control
3-FunctionE.g., shower head + hand shower + body sprays3-port diverter needed
4+ FunctionComplex multi-outlet systemThermostatic control recommended

Tip: More components = more volume or diverter controls required.

STEP 4: Select Shower Components

Choose the fixtures based on your preferences and the planned functions.

Shower Heads
● Wall Mount small shower head
● Rain Shower (ceiling or wall mounted)
Hand Showers
● Slide Bar
● Wall Mount
Body Sprays
● Fixed Body Jets
● Adjustable Spray Heads
● Touch-Clean™ Nozzles
Tub Spouts (if applicable)
Record flow rates (GPM) of each component for the next step.

STEP 5: Calculate and Confirm Total Flow Rate

After selecting your shower components, calculate the total flow rate to ensure your system can support all desired outlets.
● Add up the flow rates (GPM) of each component
● Consider how many outlets will run simultaneously
● Compare the total with the maximum output of your chosen valve type

Why It Matters:
● Exceeding valve capacity can cause weak water pressure
● High-flow systems may require thermostatic valves or multiple volume controls
● Helps determine if you need high-flow valves, multiple zones, or separate controls

Tip: Body sprays and rain showers usually have higher GPM — factor them in carefully.

STEP 6: Determine Controls: Diverter or Volume Control

Your control system depends on how you want to manage temperature and water flow.

Pressure Balance System
Single handle for both temperature and on/off
Built-in diverter supports 1–3 outlets
Only one outlet operates at a time
Simple and compact solution
Ideal for small, basic setups.

Thermostatic System
Separate temperature control + individual diverters
Each diverter controls up to 2 outlets + OFF (can also control just 1)
Allows multiple outlets to run simultaneously

You can configure:
1 diverter per outlet → full individual control
1 diverter for 2 outlets → compact layout
Best for multi-function, spa-style, or high-performance systems.
Thermostatic systems are more flexible; diverter trims have flow limits, so check specs carefully.

STEP 7: Finalize the Wall Layout

Design your shower layout to ensure optimal usability, spacing, and visual balance.

Mark:
● Valve location
● Diverter/Volume controls
● Showerhead and hand shower positioning
● Body jet arrangement
● Tub spout (if included)

Use provided layout templates or draw your own.

A: DIVERTERS AND VOLUME

Diverter and volume control trims should be conveniently accessible for all users, with flexible placement options. They can be installed close to the valve trim, outside the shower, or near the entrance, allowing users to activate components before stepping inside. Volume controls may also be positioned on the shower wall near the component they operate.

B: VALVE TRIMS

Valve trims are generally mounted around 36” from the base of the shower enclosure, approximately at waist level. You might consider placing valve trims outside the shower or close to the entry point, enabling you to turn on the water or set the temperature prior to entering the shower.

C/D/E: BODY SPRAYS

A maximum of four body sprays per loop is recommended. If more are needed, they should be divided into smaller sets. For full-body water coverage, consider placing body sprays across multiple walls when possible. Avoid directing sprays toward the shower door, as this could lead to leaks or water spilling outside.

C/D/E: BODY SPRAYS

Typically, the lowest body spray is installed at knee or thigh height, the middle spray at hip or waist level, and the highest at shoulder or upper back height. If a bench is part of the design, you might want to place a spray to target your lower back while seated or below the bench for leg massage therapy, which can help with circulation and tension relief.

E: HANDSHOWERS

The placement of handshowers is versatile and can be adjusted based on their intended purpose. When a wall-mounted handshower is used as the main showerhead, it should be positioned above the tallest user’s head while remaining reachable for the shortest user. Slide bar handshowers offer added flexibility and adjustability to accommodate users of different heights.

F: SHOWERHEADS

Position the showerhead at a height that is convenient for the primary users of the shower. It should be high enough to accommodate the tallest person, while still being accessible to the shortest user. Alternatively, you could opt for an adjustable shower arm. Avoid installing raincan showerheads directly over the drain, as this may cause the user to stand on the drain and obstruct proper water flow.

B: VALVE TRIMS

Valve trims are generally mounted around 50" from the floor of the shower, approximately 6" above the user's waist.

C/D/E: BODY SPRAYS

A minimum of four body sprays per user is recommended. If more are desired, install at least two per zone.

E: HANDSHOWERS

The placement of handshowers is versatile and can be adjusted based on the main showerhead.

F: SHOWERHEADS

Positioning showerheads at a height that is convenient for the primary user.
