Shower maximum sizes are not mandated but minimum sizes are regulated.
Shower door height code.
Threshold heights vary from 1 2 to 2 in many shower and pan designs though some have more or fewer options based on the shower or pan s size.
So says the building code.
A minimum space of 24 inches must be planned in front of a shower entry.
Shower heads are located at a standard height of 80 203 cm but can be set at a minimum height of 72 183 cm if desired.
As you enter the bathroom the door needs to be able to swing its width into the room without.
Shower floor minimum size is usually mandated to be at least 30 inches square.
That is 30 inches by 30 inches.
For assistance with your specific situation contact your shower manufacturer.
There s no doubt threshold height can be confusing.
Toilet bathroom building codes.
A minimum space of 21 inches must be planned in front of lavatory toilet bidet and tub.
The shower door needs to have an opening clearance of at least 24 inches.
Code for the doorway opening to the bathroom is 32 inches with 34 inches being the recommendation.
This is also a safety issue because users who are forced to slip around narrow door openings are more prone to slipping on the floor.
