For this week you will view all links in the week 4 module.

You will draft an elevation for every wall in your plan following the NKBA standards.

You will need to place general cabinet s of general sizes along each wall. You will need to decide the cabinet sizes. For the kitchen next week, we will use the catalogue and note each specific cabinet numbers.

For the bath this week, as there are few cabinets and they may be free-standing purchases, we will not do so or review this yet.

You do need to show height and width of cabinets, interior spaces as the shower, and fixtures.

Most of these examples you can find on the internet for “NKBA BATH ROOM DRAFTING EXAMPLES, “ do not show dimensioning of all details. You will see some with center lines for mirrors and lighting. You can use leaders to note materials or circumstances.

In the end, all items must be placed as designed in the room, so somewhere they need to be indicated. Again, usually everything is dimensioned to the center if it is a fixture, appliance, mirror, wall placed accessory.

You will see that a tile pattern may be indicated, as running bond. What you show in the elevation will be read as what is happening and should not conflict with specifications.

The basic window frame with any existing trim will be shown.

Base board or base tile will be shown unless all surfaces are tile and so you do not need added base.

You do not show decorative items that are not installed.

You would show shower or tub door style and type.

You would show hinges for showers.

You probably need to look at a basic style, as framed or unframed shower door and make a choice.

Note that we have not discussed or selected and fixtures or items yet. You can use approximate sizes and later find items to match these sizes.


Refer back to your NKBA spacing guide.

Cabinets- for master typ. 36”high

Cabinets may be 34” guest high

Sitting areas 30 to 32” at vanity high

Sink Cabinets again are 19-24” front to back including the counter surface.

Sink counters should give each person a min. of 30”, with 36” min preferred.

84” is a good length for the sink area if 2 are together.

Shower- Minimum shower inside is 9 square feet inside room by codes.

Showers need a 4”x 4” water stop or front edge unless they are flush with the floor. The inside slope is to the drain and is shown with a line or lines. These are many drain styles today.

A linear drain works well positioned toward the back with the slope in that direction.

Shower head typically roughed in at 72-78” above finished floor-AFF on the wall.

You can do an overhead shower head or rain head, but it does get hair wet.

Shower doors can come in standard heights or be custom made. Doors and windows near water in a bath room must be tempered. Frameless showers have very thick glass, ½” or so, and are very heavy and get costly.

Tubs-Typical guest tub/ shower of cheaper version in 30”w x 60” long x 15 or 16” tall floor to rim. A more expensive guest tub is approximate the same length but may be wider. It may be 17-19” high

Toilet areas approx.. 36” wide by 60” long

Toilets differ slightly but usually about 32” long, approx. 18” wide, 15 to 18” high

Backsplash typically 4” high so mirror fits easily above it. They can be higher for wall mounted faucets, but watch the mirror height in that case.

Mirrors need to start about 40” to 42” or so high. Too high and they are not usable by shorter people. They need to extend above your taller user’s face and be in proportion with the room.

Lighting- bath bar lighting goes above the mirror, but is not the greatest idea for good lighting.

Sconces work better as they give even lighting from the sides, not above. They typically are placed near 60-72” on center of the electrical box, but this depends on the fixture design.

Grab bars and accessories– Grab bars can be located residentially to accommodate a client’s use and needs- as they are not required by code. Typically around 36” is a good height. You need to have a blocking behind all grab bars- that is a solid piece of wood about 12” high and 2” thick. Plywood does not hold screws well. This needs to be indicated on walls, but can be done by a note or dashed in as hidden. Someone needs to know where they are placed if they are later needed.

Blocking can be placed behind all accessories as towel bars and TP holders. Towel bars should be placed within reach of tubs or showers as possible. Heights for all these items and placements will vary by available space, room height, and preference.

These placements should be determined by the designer and client and noted so they can be installed correctly.
