Can I shower in my basement?

As we discussed earlier, the first step is to identify if the drain you have is a traditional or French type. The easiest way to do this is by pulling the cover of the drain off. If you see sand or rocks, then it is a French drain. If you see a pipe, then it's a traditional drain.

Most of the time, French drains are used in your basement. The main reason why you can't use this for a shower is its lack of ability to drain the water quickly. Showering can cause flooding in your basement as the amount of water that pours from the shower is too much for the drain to quickly expel it.

Here is a simple video that shows how you can connect a French drain to a pipe.

You can do this yourself, but if it is too technical and you lack the skills and equipment, we recommend hiring professionals to do it for you.

Pros and Cons of a Basement Shower

A basement shower is only ideal if you are frequently using your basement. If your basement serves as a storage unit and is barely visited, then it is not ideal to have one.

You have to consider that basements are usually the coldest part of the house, showering in a cold room can be uncomfortable, especially without a heater. Leaving the shower can come as a shock in the chilly temperature of your basement.

On the other hand, if you have transformed your basement into a walkout basement or a place that serves as a secondary living room, then a shower area would be good. This would add extra value to your house as additional amenities would be attractive to prospective homeowners.

If you have also converted your basement to a bedroom, a shower would add extra privacy as you would not have to leave your room to bathe. This also adds to the value of your house.

Do you need a shower pan liner on a concrete floor?

You can shower without a pan liner underneath or on your concrete floor. However, a liner is more robust and less sensitive compared to tiles. We recommend that you still get one even your shower floor is just concrete.

Shower pan liners are there to protect your bathroom floors from leaking. It is additional waterproofing for the bathroom floor and prevents seepage to other parts of the bathroom. This helps in concentrating the water into the shower area and helps maintain a tidy and clean bathroom.

Over time, moisture can still penetrate through the cement and cracks of the floor, so a pan liner would remedy this. And if you decide to tile your bathroom, it would be easier because a pan liner is already there, they are placed under the shower pan that separates the main shower floor from its subfloor.

Many mistakenly think that tiles are what make a shower floor waterproof, it is actually your shower pan liner. Pan liners are made out of PVC turned into sheets which gives its waterproofing ability. This is also an industry-standard practice, as it adds safety and durability to your shower floor, be it concrete or not.

Can you use regular concrete for a shower pan?

Of course, you can. If you decide not to put tiles on your shower floor, plain concrete is completely acceptable. Concrete shower floors have been around ever since the 1800s and possess many pros; below are some of them.

High Water Damage Resistance

Concrete is less susceptible and more durable against water damage. If properly installed and regularly checked for cracks, concrete floors easily last longer compared to other options like teak and tiles.

Durability and Longevity

Concrete is durable to damage in general. It reacts better against chemicals, scratches, and weathering from the elements while still maintaining its overall integrity.

Low Maintenance

Concrete is very easy to clean and is not sensitive to cosmetic damage compared to other flooring options available. Although you may have to be careful with some cleaning chemicals as they can discolor cement. Bleach is one safe and very cheap cleaning agent that cleans well on cement and at the same time does not discolor it.


For the reasons stated above, maintaining concrete is cheaper compared to other flooring materials. Installing it is also cheaper and easier as you would still need concrete as your subfloor underneath tile or teak flooring if you opt to go this way.
