When shopping for a new freestanding tub, it’s easy to focus on size, shape, and style while overlooking one important technical feature: drain orientation. Understanding where the drain opening is positioned in your tub—and how it aligns with your bathroom plumbing—is essential for the longevity and proper functioning of your tub. Before you choose the best freestanding tub for your bathroom, we suggest taking a minute to learn why drain orientation matters and how it can impact your remodel plans.
To avoid having to move the drainpipe in your bathroom, the drain hole in the bottom of your tub should easily align with the existing drain location. Most freestanding tubs have either center drain or reversible end drain placement:
End Drain/Reversible Drain Tubs
A freestanding tub with an end drain has the drain hole positioned at one end of the tub floor. A left end drain is located on the left-hand end of the tub when viewed from the accessible ( entry side) of the tub, while a right end drain is located on the right-hand side of the tub.
Generally, drain location (left or right) is only critical when installing an alcove bathtub with a single finished front (apron) in a three-wall enclosure. Because an alcove tub is unfinished on one side, it cannot be flipped or rotated. Therefore, the tub drain should be on the end closest to the existing plumbing to avoid having to relocate the drainpipe.
Many freestanding tubs are designated as having a reversible end drain, meaning the drain handing can often be switched during installation simply by reversing the direction of the tub. This flexibility, effectively allowing for left- or right-hand end drain placement, is possible because freestanding tubs are finished on all sides.

Center Drain Tubs
A freestanding tub with center drain has a drain hole that is positioned directly in the middle of the tub. This drain orientation provides a balanced, symmetrical look that is ideal for modern and contemporary spa-like bathrooms. Center drain placement is also a more convenient drain location for large double slipper tubs designed for two bathers to enjoy at once. A center drain slipper tub is always comfortable regardless of whether you recline on the right or the left.

Some freestanding tubs have the drain hole centered along the length of the tub but offset to one side. These types of center drain tubs are typically referred to as either a freestanding tub with offset center drain or freestanding tub with center back drain.

Freestanding Tub Drain Placement Matters: Plan Around Your Bathroom Plumbing
Selecting a tub with the ideal drain location starts with understanding your bathroom’s existing plumbing layout. If you’re replacing a bathtub, especially an alcove tub, it’s best to select a freestanding tub with a drain hole that can be easily positioned to align with the P-trap and drainpipe. This will help you avoid costly plumbing modifications.
If you are choosing a tub for a new bathroom build, or if you have more flexibility in the placement of your tub, you may be able to select a tub with the drain orientation you prefer (that best suits the style of tub you are purchasing). For example, a two-person soaking tub may benefit from center drain placement, while a single slipper tub design typically features an end drain located near the shorter end of the tub. Reversible drain freestanding tubs are an excellent choice when you're uncertain about final placement or want to keep your options open during installation.
Choosing a tub with the correct drain orientation for your bathroom is essential for ensuring a cost-effective installation and avoiding plumbing problems down the line. Before you install a freestanding tub drain, always remember to make sure to read the manufacturer’s instructions for your tub and drain. For best results, consult a licensed plumber to ensure your freestanding tub drain is installed correctly and meets all local plumbing codes. Don’t forget to consult with your plumber or contractor early in the renovation process, as drain compatibility should never be an afterthought. With the correct drain configuration, you can install a freestanding tub that looks beautiful and works perfectly for years to come.
