Requirements concerning a bathing room:
1. Adequate dimensions and height.
2. Transport holes for carrying the bath in.
3. Facility for draining water from the floor on which the bath is to be founded.
4. Facility for steam removing.
While selecting a room the following criteria should be considered:
• a bathing room must not be too small. The minimum area should be three times as large
as the area of a selected bath type with the shape approximated to a rectangular; thus it will
be possible to build a casing and enough room will be left around the bath. That minimum
area may be chosen only if is possible to build the bath in the floor.
• if the bath cannot be sunk in the floor, the room must be higher and larger (total height of
a bath on a supporting structure is about 1m) to provide easy access to the bath and make it
possible to walk around in an unbent position. In that case the recommended minimum
height is about 3 m, and the recommended minimum area is 5 times larger than the bath
area approximated to a rectangular.
Minimum dimensions of transport holes result from engineering drawings of bath
models. A rectangular hole should have the following dimensions:
• A dimension: height of the bath with its rack
• B dimension: shorter of two linear dimensions (length or width) plus 10 cm
Since there is a risk of flooding the floor on which the bath is installed, the floor must
be provided with a floor drain connected with the sewage system of the building. If the
sewage plumb-line is situated above the floor, a gully of dimensions of 50 x 50 x 50 cm must

be constructed and a pump of capacity of at least 8 m /h (provided with a floating sensor and
connected with the sewage system) should be installed.
o
A multi-person SPA bath is an relaxing object with water of temperature of 35-40 C. Due to
that a large quantity of steam is emitted in the bathing room. To reduce evaporation the room
o
temperature must be about 24-25 C and a mechanical pressure and exhaust ventilation system
o
should be installed. If the bath is not used, the water temperature should be 25 C. The air
relative humidity should be 60-70 %. If it is not possible, a steam condenser should be
installed to keep constant air humidity, reduce the risk of damage of walls and the ceiling
resulting from excessive air humidity. If the building is air-conditioned the steam condenser
need not be installed.
