Bathroom Plumbing Design Ideas

Whether you’re looking for bathroom plumbing design ideas or need to install a new bathroom, there are several things you should know. In this article we’ll discuss some of the basics, including Centerline, Supply line (horizontal or vertical), and a freestanding tub drain.

Basics of bathroom plumbing layouts

Creating a bathroom plumbing layout is an essential part of any remodeling project. Proper layout can ensure that the plumbing system is installed properly and will save you time and money.

The layout of your bathroom will depend on the available space. If you are working with a small space, you will need a bathroom plumbing layout that is efficient. This can include a toilet and shower in the same room. If you want a walk-in shower, you will need to make some changes to your bathroom plumbing layout.

When creating a bathroom plumbing layout, you need to consider the size of your tub. A standard bathtub is 60 inches long by 32 inches wide. You may want to add a larger bathtub if you want to create more space.

Whether you are remodeling or just installing a new tub or toilet you need to know the basics of plumbing in your home. If you don’t, you might end up with a toilet that doesn’t flush properly or one that leaks all over the place. There is more to plumbing than meets the eye. Choosing the right fixtures and plumbing fittings is the key to a successful bathroom remodel. In addition, you should also know about the best place to put your new toilet.

The toilet is one of the most important fixtures in the home, so the best place to put it is in a convenient location. The ideal spot is on the floor or in the center of the bathroom, depending on your needs. If you have a tub, the tub spout should be located approximately 4 inches above the tub rim. You can make your life easier by using a carpenter’s level to mark studs before drilling. Alternatively, you can use a 2×4 cleat around the opening.

Supply line (horizontal)

Depending on the bathroom, a supply line may be in order. To get the best water pressure, a 3/4 inch copper pipe is usually the best bet. It’s also the least likely to make noise. For a complete supply line solution, the best bet is to run the line to an existing pipe, preferably one that’s already in place. Then, mark the studs and drill the holes.

To get the best possible performance, it’s worth considering a high-quality copper or aluminum pipe. This is especially true if you’re planning to run the line into a concrete slab. If you do, make sure you do a bit of jackscrewing to get the best results. Besides, the best place to get a quality pipe is at a plumbing supply store.


During the design stage, it’s important to determine the best placement for your bathroom fixtures. Specifically, the location of your main drain and the bathroom’s vents are crucial. They should be within a couple feet of each other.

While it’s not mandatory, you should consider installing a wall-hung toilet, which will free up some space. To ensure the wall-hung toilet is installed properly, get the local building authority’s approval.

You should also consider installing a vanity with a tall, narrow cabinet. This is a better option than installing a standard counter. It’s also a good idea to add a small vanity cabinet next to the vanity to maximize storage space.

You should also consider installing a grab bar at the front edge of your bathtub. It must be a minimum of 12 inches long. You should also install a similar-sized grab bar at the back wall. The other grab bar should be located eight inches above the bathtub rim.

Freestanding tub drain

Whether you’re looking to buy a new freestanding tub, or want to make your existing tub more functional, installing a freestanding tub drain is easy to do. In most cases, you’ll need to run new piping, but there are also ways to hide the plumbing.

Some homes have access under the floor, while others have an access panel that can be placed in a different room. Regardless of your situation, you’ll need to plan ahead before you start installing your freestanding tub drain.

For most freestanding tubs, there is a choice between an interior or exterior overflow. An exterior overflow is located along the side wall of the tub, while an interior overflow is located at the bottom of the basin. Some freestanding tubs also have a hidden leveling foot.
