Water Heater, Meet Your New Shower Head
The type of shower experience and the fixture options you choose will affect your water pipes, drains and hot water heater.
If you are adding a new standard shower or simply upgrading your existing shower with a new shower head or a hand shower, your existing plumbing, drainage or hot water demand will not be affected.
Jetted Shower™ or Semi-Custom Shower XO®
Delta's Jetted Shower™ works with your existing supply lines and drainage. Depending on your water heater capacity, you may need to upgrade your hot water supply. Consult a licensed plumbing contractor and/or the water heater manufacturer to determine if the size and model of your water heater are appropriate.
Delta's custom showers do not require ¾" supply lines, but if you are installing new plumbing, then you will probably want to install ¾" supply lines to provide a greater capacity.
The hot water supply is critical in determining whether the system you've designed will be a success. Your water pressure should be at least 45 psi, plus you'll need to determine if you have ½" or ¾" supply lines at your shower.
Be sure to consult a licensed plumbing contractor and/or the water heater manufacturer to determine if the size and model of your water heater are appropriate.
It's crucial to plan for proper drainage. If you have an existing drain, measure it from edge to edge. Since a single-valve system can flow up to 9 gpm, and a two-valve system could flow up to 18 gpm, we recommend two 2" drains, or one 3" drain for your system. Again, you should consult with a licensed plumbing contractor who will be doing the installation in order to get the proper guidance.
