What To Look For In A Toilet Hose Connector Supply Line
Toilet Hose Length
Length is one of the main considerations you’ll have to make when buying a toilet hose connector supply line.
In most cases, you’ll want to use the same length as your current supply line. If you have a new toilet, it may require a different supply line length. Confirm this before you remove the toilet so you have it handy. This is especially true if you go with an updated tankless toilet.
Toilet Hose Material
Probably the most important factor in your toilet hose should be the product material. You need materials that can handle the high water pressure levels that come from your toilet.
You may also need a hose that can withstand hot water temperature if your toilet has a heated seat, or you may want to use the supply line as a shower hose down the line.
In conclusion, consider both the material of the hose itself, but don’t forget about the nuts at either end. We’ll get into that once it’s review time.
What Material Are The Best Toilet Connectors Made Of?
The most common material available is stainless steel. Often, it may be braided for additional strength. For the connectors themselves, you will see brass as the most common option.
Stainless steel is strong but may succumb to corrosion over time. For that reason, you may see plastic hoses, too.
Many times, a toilet hose connector will have a stainless steel coating with a PVC pipe or rubber water pipe inside.
Got it? Ok, good. 🙂
How Long Do Toilet Supply Line Hose Connectors Last?
Toilet hose supply line hoses can last a long time without issue. However, if you look at the average lifespan you could replace your supply hose every five years.
Cheap connectors may require replacement much earlier than that, while heavy-duty toilet connectors may last much longer.
Don’t assume you need to replace your connector at the five-year mark. If it ain’t broke, don’t fix it. However, if you notice a drip leak you should replace them before it turns into a bigger one. (Like when you’re sleeping.)
Are Toilet Supply Lines Universal?
Yes, the outside length of most toilet hose connector supply lines is universal and will work for all standard toilets.
What size hose connects to toilet?
In most cases, toilet supply lines have a ⅜” connection on one end and a 7/8” fitting on the other end. These connections are considered “universal” in size.
In some rare cases, a toilet may use a ½’ supply line (such as an RV toilet).

Connecting your toilet hose connector is easy, even for novice DIY plumbers and homeowners.
Simply attach the appropriate end to the water supply pipe and connect the other end to the bottom of the toilet tank at the fill valve.
