Comprehensive Guide to Bathroom and Laundry Area Planning

Bathroom Classifications and Planning

• Classifications of Bathrooms: Bathrooms are categorized based on the specific combination and number of basic fixtures they contain:

  • Full Bath: This must include a minimum of a sink, a toilet, and a bathtub.
  • Three-Quarter Bath: This includes a sink, a toilet, and a shower, but lacks a bathtub.
  • Half-Bath (Powder Room): This includes a sink and a toilet but no bathing facilities.
  • Master Bath: A full bath that is integrated into the master bedroom area. They often incorporate design elements from the adjoining bedroom and are intended to serve as a relaxing retreat.

• Structural and Economic Considerations:

  • Placing a bathroom close to existing drainage pipes is recommended to reduce construction costs.
  • If a location is functionally unsatisfactory, the long-term benefit of convenience may justify the higher cost of extensive pipe work.
  • Planning for multiple users: If more than one person will use the space simultaneously, designers should consider double sinks and partitions to separate functional areas.

Bathroom Fixtures

• Bathtubs:

  • Shapes and Configurations: Tubs are available in rectangular, square, round, or oval shapes.
  • Standard Installation: Usually enclosed by walls on three sides.
  • Freestanding Tubs: Often feature ball-and-claw feet for a Victorian aesthetic.
  • Sunken Tubs: Can be recessed into the floor or built into a designated platform.
  • Whirlpool Bathtubs: Feature water jets designed for massaging muscles.

• Showers:

  • Tub Shower: A shower head installed above a bathtub within an enclosed area to contain water flow.
  • One-Piece Shower Units: An efficient method for adding a shower to a bathroom during remodeling.
  • Tile Showers: Aesthetically pleasing but require well-maintained grout to prevent wall leakage.
  • Enclosures: Water is contained using shower curtains, sliding doors, or swinging doors.
  • Shower Heads: Options include fixed-wall heads, adjustable/handheld models, or multiple spray head configurations.
  • Walk-In / Stall Shower: Designed for entry without stepping over a high tub wall.

• Toilets:

  • Mounting Styles: Available as wall-mounted or floor-mounted.
  • Tank Configurations:
    • High-line: Features a tank positioned above the toilet bowl.
    • Low-line: Features a tank at the same level as the toilet.
    • One-Piece: The tank and bowl form a single integrated unit.

• Bathroom Sinks (Washbasins):

  • Wall-Hung Sink: Features open space beneath the unit, making small bathrooms appear more spacious.
  • Pedestal Sink: Supported by a freestanding, often artfully shaped base that resembles a sculpture.
  • Inset Sink: Set directly into a countertop with a cabinet (vanity) beneath for storage.
  • Above-the-Counter Basin: Resembles a decorative wash bowl sitting on the counter with plumbing extending through the surface.
  • Standard Height: The standard rim height is approximately $32\,\text{inches}$ from the floor.

Cabinets, Countertops, and Utilities

• Storage and Vanities:

  • Vanity: A base cabinet that conceals sink plumbing while providing counter space and storage.
  • Bathrooms may utilize both wall-mounted and base cabinets.

• Electrical and Safety:

  • Outlets: Should have several outlets for personal appliances like hair dryers, curling irons, and electric shavers.
  • Safety: Any outlet located near a water source must be equipped with a Ground-Fault Circuit Interrupter (GFCI).

• Lighting and Ventilation:

  • Lighting: Should be wall or ceiling-mounted and controlled by wall switches.
  • Ventilation: Necessary to remove condensation from hot baths/showers and prevent mold. Options include an exhaust fan vented to the outside or an operable window.

• Flooring and Walls:

  • Floor coverings should be easy to clean and must not become slippery when wet.

Universal Design in Bathrooms

• Accessibility Features:
  • Grab bars positioned near the toilet and bathtub.
  • Wide doorways and extra floor space for maneuvering.
  • Showers equipped with a seat.
  • Elevated toilet seats added to standard units.
  • Retracting and pivoting shower doors for easier access.
  • No-sill doorless shower stalls and the use of rolling shower chairs.
  • Hand-held shower heads and single-lever controls.
  • Barrier-Free Sinks: Faucets placed toward the front and side drains to keep pipes away from the user’s knees.
  • Tiltable mirrors at the sink.
  • Faucets with retractable spray handles to allow for shampooing from a seated position.
  • Low counters to accommodate children or seated users.

Planning Laundry Areas

• Location Requirements:

  • Hot and cold water supply lines and drainage.
  • Choosing a location near existing plumbing reduces remodeling costs.
  • Electrical: A $240\,\text{volt}$ outlet is required for electric dryers.
  • Gas: A gas line is required if using a gas dryer.
  • Ventilation: Dryer exhaust must be vented outside, often necessitating a location near an exterior wall.

• Placement Options:

  • Main Floor: Near side, back, or garage entrances.
  • Kitchen/Bathroom: Often hidden behind folding doors.
  • Basement: Keeps noise and soiled clothes away from living areas, though it is less convenient.

Efficiency and Universal Design in Laundry Areas

• Efficiency Features:

  • Washable floors and proper lighting.
  • Dedicated storage for detergents and supplies.
  • Baskets, bins, or carts for sorting and transport.
  • A utility sink near the washing machine for hand laundering.
  • Rods, hooks, clotheslines, or horizontal racks for air drying.
  • Countertops or flat surfaces for folding clothes.
  • Space for an ironing board near an electrical outlet.

• Universal Design in Laundry:

  • Compact Washers: Approximately $32\,\text{inches}$ high with front-mounted controls for seated use.
  • Dryer doors that swing to the side for wheelchair access.
  • Dryers placed on platforms to reduce bending during loading/unloading.
  • Audible tones for end-of-cycle or lint screen cleaning alerts.
