Types Of Bathtub Drains (Stopper & Strainer Guide)

Here are the different types of bathtub drains including the different stopper models, strainers, if they are interchangeable, and how to choose a bathtub drain.
Bathtub drains have only one purpose — to keep water in the tub. But do you know that there are other types of bathtub drains other than the one you may be using now? And each one of them has a specially designed stopper.

Bathtub Drain Stopper Types 

Bathroom area with tile wall, acrylic tub, faucet, and drainHave you ever experienced your bathtub getting clogged? If not, you might not be aware that your bathtub drain has a uniquely designed stopper.

Knowing the type of stopper your bathtub has will save you the hassle and the stress later. You won’t have any problem finding what you need when you need them. So here’s a list of the different bathtub drain stoppers

Push And Pull Drain Stopper

Individual pulling lift type of bathtub drainThis type of drain plug has a knob on the top cap that serves as the open/close mechanism. When you want to drain the water, you pull it up. And when you want to fill the tub with water, you push it down.

The push and pull stopper is installed by attaching the stopper’s body to the drain using a setscrew found beneath the top cap. The stopper’s simple design requires minimal care. 

Lift And Turn Bathtub Drain

Also called the lift and lock, this stopper has a tiny knob on its cap. You can use this to open or close the plug by twisting it. If you want to open it, lift the knob and turn it in a counter-clockwise motion. If you want to close it, twist it clockwise until it goes down. Be careful not to close the stopper tightly because it might get stuck. 

You can install the lift-and-turn stopper by installing a setscrew into the threaded center of the drain crossbar. You can find the setscrew under the top cap of the plug.

Just like the push and pull stopper, its practical design requires little maintenance. All you need to do is clean the plug from time to time to prevent dirt from accumulating. 

Flip Switch

The flip-switch stopper has a toggle lever on top of the plug which can be moved from side to side to open or close it.

It is one of the easiest to install because it does not require any tools. All you need to do is push it into the drain, and the built-in O-rings keep it in place and act as a watertight seal. 

Tip-Toe Tub Drain

Also called a toe-touch or toe-tap stopper, this plug is similar to the lift-and-turn and push-and-pull stoppers. It is also installed just like the first two plugs. The only difference is that the tip-toe has a spring-loaded design.

Using it is also much simpler — you open or close the stopper by pushing it with your toe. The tip-toe plug also requires little maintenance. But the spring might wear out after quite some time and needs replacing. 

Pop-Up Tub Drain

If you lift the lever, the connecting rod in the overflow drain pipe moves. As the rod moves, the rocker arm connected to the pop-up stopper rotates. The spring at the bottom of the connecting rod controls the stopper. 

Cleaning the pop-up stopper is a bit complicated. You have to remove the stopper and the rocker arm from the drain opening and the rod linkage from the overflow pipe. 

Tub Strainer

Trip Lever Bath Drain

Bathroom with white wall, tub, drain, and faucetA trip lever is used in many types of bathtubs. It has a lever on the overflow plate found in front of the tub. This plug type has a strainer instead of a pop-up stopper in the drain opening. 

How Does a Trip Lever Bath Drain Work: The trip lever drain has different parts that work together to release or stop the water. First is the small up/down lever found on the overflow plate of the bathtub.

This lever controls a connecting rod found inside the overflow pipe, which moves up and down when you move the lever. At the bottom of the plug is a type of plunger that also serves as a weight to seal the drain opening. 

When you push the lever down, the plunger is lifted, and the water gets drained. When the lever is up, the plunger goes down and seals the drain. If the tub overflows, excess water can flow through the overflow tube and drain away because the plunger is hollow. 

Clawfoot Tub And Overflow Drain

These types of tubs are freestanding and have the overflow attached outside the tub together with exposed pipes. Also, both the pipes for the water source and the drain enter through the floor. 

 Are Bathtub Drains Interchangeable?

Bathroom with white walls, tub, faucet, and drainPlumbing standards are set by the industry, so they are the same including the drains. But this only applies to the width of the drains, pipes, and other fixtures. The length is still different depending on the type of plug you use. 

A bathtub drain is around 1-5 in. in diameter and can fit any bathtub that has 14 – 26 inches in depth. The drain size is designed to fit the P-trap. However, P-traps don’t have a standard length, so you need something that fits your plumbing. 

How Do I Choose A Bathtub Drain?

Bathtub with faucet, and drainAlong with learning how to choose the best bathtub, one must discover the right kind of drain to use. Bathtub drain sizes are standardized, so you don’t have to worry about the opening. 

But, you need to take note of the other components like the P-trap and the drain pipe. After that, you need to consider the style of the drain. You should add an overflow drain also to prevent the bathtub from overflowing. 

The building code of the area where you live might affect the type of drain you choose. Look at the guidelines and regulations for the size of the components like the drain pipe and P-trap. Read more about bathtub dimensions here.

Waste And Overflow Kits

Bathroom with tub drain, support bar, and accent wallYou can choose from two types of waste and overflow kits — common and glue in.

Common Waste and Overflow Kit: Common waste and overflow kits are compatible with bathtubs that have an access hole that goes through the floor or an adjacent wall. The overflow body of this kit has a long tube that makes the vertical riser from the overflow down to the Tee. 

The top portion of the Tee has a slip joint fitting so you can cut the tube of the overflow to fit tubs with different depths. 

There’s another slip joint fitting found at the side opening of the Tee. Its purpose is to adjust the waste arm from the drain shoe easily. Then, the tailpiece of the Tee drops down to the P-trap.

Glue In Waste and Overflow Kit: The glue-in overflow kit is compatible with bathtubs that are fully skirted and has no access panel. It consists of a tee, a casr overflow body, and a cast tub shoe.

The connecting lines are custom fitted from standard schedule 40 DWV grade pipe and glued in place. The glue-in kit also needs a glue-in P-trap. One of the biggest advantages of this type of overflow kit is its durability. It has no or little chance of leaking once it is glued in place. 

Different Drain Styles

Metal drain stopper for bathtubsWhen choosing a tub drain, you also need to consider the style. Here are the different types of drains and how they work:

Straight Drains: These bathtub drains connect directly to a metal drain pipe or hub adaptor in the floor instead of a P-trap. It comes in a wide range of styles and finishes. Straight drains are easy to install and can be mostly done as DIY. 

Tower Drain: These are often used with clawfoot tubs that have overflow openings. They have a pop-up release controlled by a lever on top of the drain pipe. 

Extended Straight Drain: This type of drain comes in three options — lift and turn, pop-up, and chain and plug. Extended straight drains are often used with freestanding bathtubs. Since they are external, you should find a style that complements your tub. 

Extended Straight Drain with Swivel Head Overflow: This drain type has a pop-up drain and an exclusive design that prevents overflow water from spilling on the floor. You can pair this drain type with most freestanding tubs no matter what style or thickness they may have. 

Whether you are installing a new tub or renovating an existing one, knowing each component of your bathtub is important. It will save you the hassle of getting to and from the store to change something if you got a component wrong. If you are not sure, you can always ask your plumber or installer what the best is for your tub.
