What Comes Standard with a Toilet Tank and What You Might Need to Buy Separately

Shopping for toilets, toilet tanks, or parts of a toilet tank can raise a lot of questions. What’s included? What else do you need to order? At SquarePeg, we make it easy to know exactly what comes standard with each type of toilet product. Here’s a breakdown of what you’ll get (and what you might still need) when purchasing a one-piece toilet, toilet bowl, or toilet tank.

One-Piece Toilets: All-In-One Convenience

If you're looking for a fully equipped, ready-to-install option, a one-piece toilet fits the bill! These units come standard with everything you need: flush handles, internal valve components, toilet seat, and toilet lid. No need to worry about tracking down extra components — just install and go. It’s an easy way to upgrade or replace your toilet with confidence.

Toilet Bowls: Check the Description Carefully

When purchasing a toilet bowl on its own, there are a few more details to consider. Some bowls include seats and/or lids, while others do not. At SquarePeg, we clearly state this in each product description, so you don’t need to guess. Flush handles, fill valves, flush valves, and flappers are not included with the bowl, so you’ll need to purchase those separately.

The good news? Mounting bolts for installation are typically included with the bowl purchase, and this will also be stated in the online listing. Just make sure to read the full product description so you’re not caught off guard.

Toilet Tanks: Match Matters

The parts of a toilet tank include essential internal components like the flush handle, fill valves, flush valves, and flappers. In most cases, you're covered for a smooth flush and secure fit. However, if you’re buying a tank to pair with an existing bowl or purchasing a new two-piece unit, it’s crucial that the two parts are compatible.

Each tank is designed to match specific toilet bowls, and SquarePeg makes it easy to check compatibility in the product details. While buying tanks and bowls separately might seem complicated, it can actually save you money over time. If just the bowl cracks or the tank malfunctions, you won’t need to replace the whole unit, just the part that needs attention.
