There are many advantages to adding a bathroom to your basement. For example, it is convenient not to go upstairs every time nature calls, your guests don't have to share your bathroom, and your children or elderly loved ones don't have to climb the stairs to use the bathroom. However, due to the location of the basement below the main drainage line of the house, gravity-based toilets may not work best here. Some of the options to consider include:
This is the most obvious solution as far as basement toilets are concerned. These toilets use air pressure to force waste through the drainage pipes instead of relying on gravity. The air pressure results from the water coming into the tank. This means more water will accumulate in the bowl, which increases the flushing power of the toilet.
These toilets are designed with a pump that forces the sewage into the sewer line upstairs or septic tank line. To do this, a sewage ejector toilet comes with a small tank that holds the effluent temporarily before it is pumped upward. There are designs that allow other wastes, such as bathtub water, to drain into the same tank so that it can be pumped upstairs.
Whereas normal toilets channel their wastes downward, the macerating upflushing toilet is designed to flush its wastes upward. It works more or less like the sewage ejector, but the difference is that it doesn't have a temporary sewage tank.
Since solid wastes aren't easy to force upwards, the toilet comes with a macerator that grinds the solid wastes for ease of flow. If you have decided on a macerating upflushing toilet, opt for the newer ones that are powered by electricity and are more efficient that the traditional ones that relied on water pressure.
Composting toilets can also work excellently in the basement. The only problem is that they are only meant for toilet waste – they aren't suitable for other effluents such as water from the shower. A composting toilet uses an aerobic processing system to compost the toilet wastes, mostly into fertilizer that can be used to grow plants. Check with the local authorities if you can use the compost in your garden.
Adding a toilet to the basement is clearly complicated; it's not the kind of work you want to tackle with your limited DIY skills. Hire the right technician to evaluate your house's plumbing/drainage system to help you install the right toilet.
