Wall Mounted Toilets
The toilet may not be the most glamorous item in your bathroom but it is certainly the most necessary. Universal Design targets the whole family and the idea is to make your home usable by people of varying ages and abilities. However if you are thinking about universal design at this point it is probably because you are getting older (wiser too), are helping to remodel your parents home, or have persons with varying degrees of disabilities living with you. Of all of the rooms in your house, the bathroom requires the most physical exertion. So how do wall mounted toilets play into this? Let's take a look:
A mature-friendly bathroom is a good idea because we all recognize that as we get older we lose some mobility and strength. This doesn’t mean that your more accessible bathroom has to look institutional. With a sound design and some aging-friendly products, you can make-over your bathroom so that it is both usable and good looking.
Standard toilets are often too low for people with limited leg or joint strength. If you can’t quite picture this yet, I want you to think about what it is like to try to get up from a low toilet seat if you are wearing skates. Not so easy, and while you may not have wheels on your feet you still might experience problems with slippers that slide or finding that you lack the arm strength to lever yourself up without a bar to hold on to. Moderate height is 18 inches but very few moderate height toilet seats are available. Most are low (15 inches) to special or ‘handicapped’ units that are very high at (19-20 inches). It is possible to install height adaptors that snap onto a toilet and can raise the seat up 2-5 inches, and some models come with grab bars to lend extra support.
There are new breeds of toilets available today that can make it easier for everyone to use. Raised toilets seats have become so popular that many manufacturers are offering them in all of their major lines and colors. A few inches can make a big difference when it comes to sitting down or getting up. Another option is a wall mounted toilet that can be installed at any height and provide more clear space for approach and transfer if you are using a wheelchair or walker. Toilet seats in a “dream” bathroom would feature a wall mounted arrangement. Think about how easy it would be to clean!
A wall mounted toilet creates better access by reducing how far the toilet extends out into the room. In a small bathroom a wall-hung or an in-wall toilet can make the difference between the bathroom being wheelchair accessible or not. A wall-hung toilet mounts to the wall framing and removes the need for the toilet foot or base.
Like it or not, most bathrooms are small. A couple of inches here or there can mean the difference between being able to use the facility or not.
Whether you choose a floor mounted or wall-mounted toilet will depend on the plumbing in your bathroom. The drain line in your bathroom is the pipe that takes the water and waste from your toilet bowl to the sewer or septic tank and this can either be a floor discharge or a wall discharge design. This is something you can address when you remodel.
You now have some things to think about when you start browsing around your favorite home improvement store. When choosing a toilet for a mature-friendly bathroom you have several options: a raised-height toilet, a wall mounted toilet, or an in-wall tank toilet.
