Designer Shower Systems by BathSelect

Design teams need to assess the following conditions before final selection:

BathSelect luxury shower systems may include rainfall heads, handheld sprayers, body jets and several selectable functions. The plumbing engineer must establish whether the diverter permits one outlet at a time or concurrent operation because that decision directly influences supply sizing and hot-water demand.

Sequential use may suit smaller branches. Assemblies that activate multiple functions together can require larger supplies, a higher-capacity valve body and greater recovery from the water-heating system.

Construction documents should require automatic compensating shower valves to be tested to the standard adopted by the local jurisdiction. ASSE 1016 addresses devices that control water temperature at showerheads, handheld showers, body sprays and related outlets.

BathSelect offers thermostatic shower mixer valves for concealed and multifunction applications. Each selected model should be reviewed for:

The maximum-temperature limit stop should be field adjusted during commissioning. A thermostatic valve must not be assumed to remain correctly calibrated immediately after rough-in.

Consider this illustrative design basis:

These figures are an engineering example rather than universal product ratings. Published data for the selected fixture must govern the final design.

At 8.6 gpm, undersized branches can cause weak spray projection, unstable temperature, excessive noise or unequal distribution among body jets. A dedicated manifold with balanced branch lengths can improve consistency. Pressure-drop calculations should include piping, fittings, the mixing valve, diverter, hoses and terminal outlets instead of relying solely on static pressure measured at the building entrance.

EPA WaterSense-labeled showerheads are limited to 2.0 gpm and must satisfy water-efficiency and spray-performance criteria. Body sprays are treated separately within the WaterSense specification, but their contribution still belongs in the total system-demand calculation.

BathSelect rain shower heads can provide efficient overhead delivery, while dedicated shower massage jets may be incorporated for spa-oriented projects.

The 2010 ADA Standards generally require accessible shower compartments to include a spray unit with a hose at least 59 inches long that can operate in both fixed and handheld positions. Controls and spray units must fall within the reach range applicable to the selected shower configuration.

A decorative control panel should not be placed where a grab bar, glass panel, cantilevered shelf or seated user will obstruct it. Where accessibility provisions apply, controls should operate without tight grasping, pinching or wrist twisting.

Compliance must be checked against the adopted code and project type. Hotels, healthcare settings, residential units and institutional facilities may apply different requirements to accessible rooms and bathing fixtures.

The design team should establish:

Electronic valves and drivers should not be permanently concealed without a service route. In hospitality projects, access from an adjacent closet or corridor can reduce disruption when maintenance is required.

During early design development, the architect selected a three-function package primarily for appearance. Plumbing review confirmed that the specified diverter allowed simultaneous use. Modelling the aggregate demand across stacked guest-room branches showed that preliminary pipe sizes and domestic hot-water assumptions were inadequate for peak occupancy.

The team increased riser capacity, limited selected outlet combinations, introduced accessible valve-service panels and standardised rough-in dimensions among room types. These measures reduced installation variation and prevented already tiled assemblies from being opened during commissioning.

The lesson is clear: designer shower systems belong within the building’s domestic-water infrastructure and should not be finalised through a one-off finish-selection exercise.

ASME A112.18.1/CSA B125.1 covers plumbing supply fittings that may include showerheads, handheld showers, valves and body sprays, depending on the product category and the edition adopted by the authority having jurisdiction.

BathSelect also provides commercial automatic sensor showers for demanding public or institutional settings where controlled operation, hygiene and durability are central criteria.
