At the back of the sink or toilet the ceiling height can be as low as 60 inches.
Bathroom door height off floor.
Toilet bathroom building codes.
The standard recommendation for towel bar height is 48 from the floor to the center of the bar i tend to hang mine between 44 48 high.
The standard height of the rough opening for a door is the door height plus 2 5 8 inches.
Interior door height off floor.
The ceiling in your bathroom must be at least 80 inches at the front of the sink or toilet and inside the shower.
The shower door needs to have an opening clearance of at least 24 inches.
This is because shower doors often are made of materials such as glass that can easily break and pose a danger.
The height of common doors is 6 feet 8 inches.
So says the building code.
Place the door handle at about 900 millimetres off the floor or wherever is comfortable for.
When determining the best towel bar height for your space you need to take into consideration how your bathroom is laid out sometimes the placement of outlets and light switches can affect things.
A 450 millimetre wide fixed panel and a 600 millimetre wide door panel work well for a typical 1500 millimetre tub.
The standard i use is 1 2 over finish floors 3 4 is acceptable.
The awi gives no minimum but a maximum of over 3 4 is unacceptable.
That is a lot of room for unlevel you have there.
I just took a quick look at some of standards and regulations governing door undercut which is the distance between a door and finished floor as opposed to clearance which is door to sub floor.
I prefer to run shower enclosure glass to the full ceiling height with the door just slightly below to allow for a free swing as i did in the bathroom shown here.
To fix the issue the doors need to be removed bottom of the jambs cut and reset the door.
