GROHE…THE CUSTOM SHOWER SPECIALIST ®
IMPORTANT NOTE: The information contained within this workbook is intended as a general guideline. As
any good plumber knows, every installation presents its own unique variables, such as water pressure, drain
venting, etc. This workbook is a companion piece to the GROHE Shower Products and Systems Brochure.
Refer to the brochure for a complete color presentation of GROHE shower and thermostatic temperature control valve products. For specific questions on GROHE products contact GROHE’s Technical Service team.
Custom showers (or multiple-head showers as they are
sometimes referred to) have been a cornerstone of the
GROHE line for many years. In fact, GROHE was among
the first to promote the concept over 15 years ago. There
are two reasons why GROHE’s shower systems have been
so widely accepted:
• GROHE manufacturers the industry’s most reliable,
accurate thermostatic temperature control valves;
• GROHE offers a wide variety of shower components
that can be configured to any inspiration (whim) the
homeowner or designer may have.

YOUR FUTURE GROHE CUSTOM SHOWER
Originally, showers were used solely for hygienic reasons. But with the rise in popularity of hand
showers and body sprays, showers are now designed for stress reduction, relaxation, therapy, and
even washing household pets. Here are a few questions to ensure that the custom shower design
meets the needs of the user.
l Is selecting a comfortable temperature before you
enter the shower a consideration?
Yes
l What would you like your “dream shower” to do?
No
l Who will be using the shower? Is child safety
with regards to hot water a concern?
l Would you like a variety of spray patterns from
your shower head? (check all spray patterns desired)
l Do you get aches and pains that could be
soothed by pulsating shower sprays?
Yes
No
l Is quietness of the shower system and spray a
consideration?
Yes

ABC’s OF CUSTOM SHOWER DESIGN
Although installing a custom shower involves several tasks, they’re just not that difficult…that is,
if you keep some basic rules in mind. Following are the ABC's of custom showers as compiled by
the GROHE Technical Service team:
A. How Many Shower Outlets?
This is simply a matter of arithmetic. The sum total
flow rate of all shower outlets (shower heads, hand
showers, or body sprays) combined cannot exceed the
maximum flow rate of the thermostatic temperature
control valve at the given water pressure (see flow rate
chart below.) Exceeding the capacity of the valve will
only lower the overall performance of the custom
shower, and thereby lower your customer’s satisfaction.
For example, all GROHE shower products are
restricted to a maximum of 2.5 gpm at 80 psi. Five
shower outlets would have a flow rate of 12.5 gpm (5
x 2.5 gpm). The Grohtherm 34 124 has a flow rate of
18 gpm at 45 psi. Obviously, this GROHE thermostatic
temperature control valve would do the job.
Note 1: Water pressure is a critical factor in a custom
shower. GROHE recommends at least 45 psi for a
system with 3 or more outlets.
Note 2: This is a biggey! While it is against national
code, on occasion, homeowners have reportedly
removed the restrictors from their shower heads.
(This is a practice which we discourage. It upsets the
balance of the system.) If restrictors are removed,
GROHE shower heads, hand showers, or body sprays
will flow (on average) 4.5 gpm unrestricted. If a
homeowner has removed the restrictor from a GROHE
28 206 Deluxe Champagne Spray shower head, the
28 373 Rainshower shower head or the 28 375 Retro
Rainshower shower head, the flow will be up to
15 gpm.

**GROHE recommends the use of a pressure reducer in homes with pressures above 72.5 ps i.

Note 3: If the number of shower outlets desired is
more than one valve can accommodate, it will be
necessary to use two (or more) thermostat valves.
With two valves, if two people are using the shower at
the same time, each person can select the temperature
he or she prefers. When more than one 3/4” valve is
necessary GROHE recommends that water supplies be
1” or larger.
Note 4: Whenever designing a custom shower where
a well is involved, make sure you know both the flow
and pressure capacity of the well/pump system. A
pump supplying 10 gpm at 30 psi might be fine for a
simple tub/shower, but it’s never going to do the job
for a 5-head custom shower with a 3/4” thermostat
valve. Either you will have to break the homeowner’s
heart, or upgrade the well pump.
B. The Valve
It should always be a thermostatic temperature control
valve, and preferably a 3/4” thermostat valve. We
recommend the GROHE Grohtherm 34 124 or 34 125
which can be used with a variety of trim designs and
finishes (trim sold separately). These valves will flow
enough water to satisfy most needs, but critically
important, a thermostat valve will control the
temperature automatically as well. Temperature
control in a custom shower is much more than a
performance consideration, it is a safety consideration.
A two handle valve system will flow more water, but
without any constant, practical or safe temperature
control at all!
Remember, 1/2” supplies plumbed into a 3/4” valve
will still increase water flow. (In this situation, a 3/4”
valve will not perform at full capacity but will still flow
more than a 1/2” valve.) It is not necessary to have
3/4” supplies to use a 3/4” valve, though when this is
an option it is preferred.
C. The Drain
Always determine the drain capacity. Two Grohtherm
34 124 valves can flow 36 gpm or more when
combined (depending on pressure). That means that
in 5 minutes you could have 180 gallons of water
waiting to go somewhere! Will the drain empty the
shower pan (floor) fast enough? Two 2” drains or one
3” drain is recommended, especially when an
accessible shower pan is installed. (Drain capacity
assumes proper venting.)
D. Hot Water
Remember the bigger the custom shower, the more
hot water that will be required. A ten-outlet custom
shower is hardly worth the effort and expense if there
is nothing but cold water after two to three minutes.
A 50 gallon water heater will supply a four-outlet
custom shower for approximately 8 minutes (assuming
shower heads are restricted and all are turned on for
the entire duration)...is that enough for your client?
For best overall customer satisfaction, make sure the
water heater output is sufficiently matched to your
customer’s showering habits.
E. Volume Controls
Custom showers are generally designed with separate
volume controls (on/off) for each outlet or bank of
outlets -- typically, one volume control for the shower
head, one for the hand shower, and one for three body
sprays. (OOPS! There is no typical in a “custom”
shower.)
Volume controls, of course, have their own flow
rates. We recommend using 3/4” volume controls
throughout the system...GROHE 3/4” volume controls
flow 16 gpm at 45 psi. If cost is a concern, 1/2”
volume controls can be used, however, the flow rate is
reduced to 8 gpm at 45 psi. Remember, the combined
flow rates of the outlets cannot exceed the volume
control flow rate without a reduction in performance.

ABC’s OF CUSTOM SHOWER DESIGN
F. Body Sprays
Any configuration of two or more
body sprays requires that they be
plumbed with a balancing loop (see
illustration at left.) This technique
insures that each outlet delivers
the same spray volume and
temperature.
G. Valve Outlets
1/2” Balancing Loop
GROHE thermostatic temperature
control valves are designed with
two mixed water outlets. In a
shower-only system (this includes
multiple-head systems), the bottom
outlet should be plugged.
If a tub filler is part of the
system, plug the top outlet and
install a Twin Ell (see illustration at
left) on the diverter tub spout to
supply the shower outlets. Using
both outlets simultaneously can
cause inconsistency in temperature.

POSITIONING GUIDE FOR
CUSTOM SHOWER COMPONENTS
A User height is one of the critical factors in setting the
A)
heights of shower outlets in the custom shower...and all
users should be taken into account. Children and anyone confined to a wheelchair can be accommodated
with a height adjustable hand shower bar.
B The shower head should be set at a level above the
B)
head of the tallest user but not out of reach for shorter
users (excluding children). The reasons are simple:
taller users should not have to duck or crouch to rinse
their hair; shorter users need to be able to reach the
shower head so that they can manually adjust the spray
pattern of the head and the angle of the water flow.
C)
C The top body spray is normally set at shoulder or
back height. It should not spray horizontally into a
user’s face or ears.
D)
D The middle body spray is normally set at waist or
hip level.
E)
E The lowest body spray is normally set at thigh or
knee height.
Note: Body sprays, no matter how many are installed,
are intended, primarily, to have the entire body covered
by water no matter which direction the user faces.
Body sprays should be installed on a different wall from
the shower head, whether facing it or perpendicular to
it, so that the body sprays flow from a different angle
from the shower head. Do not aim body sprays at the
shower door.
F The thermostatic temperature control valve should be
F)
set at approximately waist height and should be easily
accessible.
G)
G Volume controls (the on/off valves) should be easily
accessible to anyone using the shower, usually about
waist high and slightly above the thermostat valve
(depending on piping requirements).
