Plumbing fixtures, other than water closets, shall be provided with approved strainers.
Exception: Hub drains and standpipes.
The installation of fixtures shall conform to the following:
- Floor-outlet or floor-mounted fixtures shall be secured to the drainage connection and to the floor, where so designed, by screws, bolts, washers, nuts and similar fasteners of copper, brass or other corrosion-resistant material.
- Wall-hung fixtures shall be rigidly supported so that strain is not transmitted to the plumbing system.
- Where fixtures come in contact with walls and floors, the contact area shall be water tight.
- Plumbing fixtures shall be usable.
- Water closets, lavatories and bidets. A water closet, lavatory or bidet shall not be set closer than 15 inches (381 mm) from its center to any side wall, partition or vanity or closer than 30 inches (762 mm) center-to-center between adjacent fixtures. There shall be a clearance of not less than 21 inches (533 mm) in front of a water closet, lavatory or bidet to any wall, fixture or door.
- The location of piping, fixtures or equipment shall not interfere with the operation of windows or doors.
- In flood hazard areas as established by Table R301.2(1), plumbing fixtures shall be located or installed in accordance with Section R322.1.7.
- Integral fixture-fitting mounting surfaces on manufactured plumbing fixtures or plumbing fixtures constructed on site, shall meet the design requirements of ASME A112.19.2/CSA B45.1 or ASME A112.19.3/CSA B45.4.
Waste receptors shall be of an approved type. Plumbing fixtures or other receptors receiving the discharge of indirect waste pipes shall be shaped and have a capacity to prevent splashing or flooding and shall be readily accessible for inspection and cleaning. Waste receptors and standpipes shall be trapped and vented and shall connect to the building drainage system. A removable strainer or basket shall cover the waste outlet of waste receptors. Waste receptors shall be installed in ventilated spaces. Waste receptors shall not be installed in bathrooms, attics, crawl spaces, interstitial spaces above ceilings and below floors or in any inaccessible or unventilated space such as a closet. Ready access shall be provided to waste receptors.
- Open hub waste receptors shall be permitted in the form of a hub or pipe extending not less than 1 inch (25 mm) above a water-impervious floor, and are not required to have a strainer.
- Clothes washer standpipes shall not be prohibited in bathrooms.
Plumbing fixtures that are used for washing or bathing shall not be used to receive the discharge of indirect waste piping.
- A kitchen sink trap is acceptable for use as a receptor for a dishwasher.
- A laundry tray is acceptable for use as a receptor for a clothes washing machine.
Shower compartments shall have not less than 900 square inches (0.6 m2) of interior cross-sectional area. Shower compartments shall be not less than 30 inches (762 mm) in minimum dimension measured from the finished interior dimension of the shower compartment, exclusive of fixture valves, shower heads, soap dishes, and safety grab bars or rails. The minimum required area and dimension shall be measured from the finished interior dimension at a height equal to the top of the threshold and at a point tangent to its centerline and shall be continued to a height of not less than 70 inches (1778 mm) above the shower drain outlet. Hinged shower doors shall open outward. The wall area above built-in tubs having installed shower heads and in shower compartments shall be constructed in accordance with Section R702.4. Such walls shall form a water-tight joint with each other and with either the tub, receptor or shower floor.
- Fold-down seats shall be permitted in the shower, provided the required 900-square-inch (0.6 m2) dimension is maintained when the seat is in the folded-up position.
- Shower compartments having not less than 25 inches (635 mm) in minimum dimension measured from the finished interior dimension of the compartment provided that the shower compartment has a cross-sectional area of not less than 1,300 square inches (0.838 m2).
The adjoining walls and floor framing enclosing on-site built-up shower receptors shall be lined with one of the following materials:
- Sheet lead;
- Sheet copper;
- Plastic liner material that complies with ASTM D 4068 or ASTM D 4551;
- Hot mopping in accordance with Section P2709.2.3; or
- Sheet-applied load-bearing, bonded waterproof membranes that comply with ANSI A118.10.
The lining material shall extend not less than 2 inches (51 mm) beyond or around the rough jambs and not less than 2 inches (51 mm) above finished thresholds. Sheet-applied load bearing, bonded waterproof membranes shall be applied in accordance with the manufacturer’s instructions.
Fixture fittings and faucets that are supplied with both hot and cold water shall be installed and adjusted so that the left-hand side of the water temperature control represents the flow of hot water when facing the outlet.
Exception: Shower and tub/shower mixing valves conforming to ASSE 1016 or ASME A112.18.1/CSA B125.1, where the water temperature control corresponds to the markings on the device.
