Can You Install a Shower Filter on a Rainfall Shower Head?

Thinking about adding a shower filter to your bathroom but not sure if it will work with your current rainfall shower head?

In most instances, installing a shower filter on a rainfall shower head is possible. However, there are a few things to keep in mind before making your purchase.

Shower Filter Design

The design is the most important consideration to consider before buying a shower filter, especially if it is installed on a rainfall shower head.

Since rainfall shower heads are attached to a ceiling-mounted or extended shower arm, there are limited options for shower filters. Learn about all the different types of shower arms here.

Bulky models such as the Aquasana AQ-4100 or Kohler Aquifer simply require ample clearance for the separate filtration canister and cannot be installed on a rainfall showerhead. On the other hand, compact designs like the AquaBliss SF100 or Sprite SL2-CM Shower Filter add minimal bulk as they attach right to the shower arm.

Added Length from Shower Filter

Aside from compatibility, it’s also essential to consider the length the filter will add between the shower arm and shower head. As a general rule of thumb, you want to have at least six inches of clearance between your head and the shower head.

Most in-line shower filters will add about 3 to 5″ in length between the shower arm and the head, so keep that in mind when deciding. We recommend using a tape measurer to get an accurate idea of how much-added length your new filter will create before purchasing.

Ease of Changing the Filter

You’ll find in your research that cartridges for shower filters will either be in the housing unit or a separate side chamber:

A shower filter with a side chamber makes removing and replacing the filter much more manageable. When the cartridge is in the shower filter, you’ll have to twist it off with the rainfall shower head attached, which can be challenging if your rainfall shower head is heavy and made from solid brass (like most of them are).

Don’t Forget to Match Your Fixture Finish

Unfortunately, the finishes that shower filters are available in are somewhat limited. So you may need to make some tough decisions when choosing a style in tandem with the filtration quality you’re looking for.
