If you’re thinking of installing a downstairs toilet, you might be wondering if it’s a good idea and whether it’s worth it or not.

An extra toilet can prove to be very useful for you, your family, and guests. It could be the missing link to make a house your dream home. It even helps to add value to your property if you’re looking to move in the future.

You might still be in two minds about installing a downstairs loo, and that’s ok. To help you decide, here are the pros and cons of adding one. 

The pros to installing a downstairs toilet

You can keep visitors downstairs

If you entertain guests regularly then you will know all too well the issue when people use the only toilet in your house. They have to wander upstairs, treading mud into your lovely carpet or wandering around your bedroom. It’s understandable that you don’t want them to go up there, especially not into your bedroom. A downstairs toilet means your visitors no longer need to go upstairs, giving you that privacy and peace of mind that you want.

The downstairs loo also means they’re never too far away from the conversation and entertainment either!

You offer easy toilet access for the elderly and disabled

If your guests are elderly or disabled, going up the stairs to use the toilet is neither easy nor comfortable. A downstairs toilet makes life easier for them. 

It’s easier for everyone

Fitting a downstairs toilet near the living area means you and your family don’t have to go up and down all day. If you’re potty training your kids, it’s simple to just pop them in your new downstairs loo, instead of going upstairs constantly. It’s more convenient for everybody in the house.

Less chance of queues to the loo

An additional toilet makes it less likely for you or your guests to queue for the toilet. Whether the downstairs or upstairs toilet is occupied, it means there’s another option.

Adds value to the property

Having a downstairs toilet is not only convenient but it also adds value to your property. It can add as much as 5%!

Cons of adding a downstairs toilet

Fitting a downstairs toilet does give you several advantages. However, there are a few disadvantages to consider as well.

You may be limited on space

Fitting a downstairs toilet means considering where it will be installed. Will you be converting a space or creating a new area of your home for the toilet? To convert or extend essentially. 

If you’re converting an existing space, then will you be converting a garage into a toilet, or will you be cleverly using the space under the stairs? If you’re converting the space under your stairs, then your new room may be small, limiting the space available to get creative. If that’s the case, definitely check out these smart bathroom storage ideas to free up limited space.  

There could be an additional cost for lighting 

Unless you have a corner with a window where the toilet can be fitted, it’s going to be dark even during the day.

Wall insulation work may be needed (additional building work)

Is your downstairs toilet fitted in an extension or onto an exterior-facing wall? Then you may need wall insulation, which could be an unexpected cost to you. 

Without wall insulation you may face several problems with your toilet; it will get cold in the winter and you may have dampness to deal with inside and out. The correct wall insulation is key in your new downstairs toilet build.  

Unfortunately, additional building work can be an unexpected expense with many home renovation projects. Do your best to spot where there could be additional costs in your project, and have a buffer in your budget – then additional work needed won’t be such a hard hit on you.

Drainage could be expensive

If the only space for a downstairs loo is away from the main drainage pipe then you will need to install the connecting pipes. You may even need a macerating or an upflush toilet, like Saniflow.

If you’re active or on a diet – less steps recorded on your exercise app!

Without the need to go upstairs constantly to go to the loo, a downstairs toilet will significantly reduce the steps you make in a day – this is either a pro or con to you!

As you can see, a lot of the cons of installing a downstairs toilet may not even impact your decision. 

If you’re still looking to go ahead with your new downstairs toilet installation project, then what else should you be aware of?
