Pros and cons of a macerating toilet

When you are in the market for a macerating toilet because your plumbing system does not have a downward drainage facility, it’s important to understand the benefits and downfalls before you spend your money. Don’t worry, the benefits of this project greatly outweigh the negatives. Unfortunately, nothing is ever perfect, but it doesn’t take away from how great this product can be.


  • The biggest benefit that you receive when you purchase a macerating toilet is that they can be installed anywhere in the house whether you have a traditional plumbing or drainage system or not.
  • These toilets are great alternatives for areas that were never intended to have a toilet. When you have kids, need that extra bathroom and have an empty space under the stairs, the attic, basement, etc. it’s a great option that can help a parent out immensely.
  • Macerating toilets are portable. Yes, you literally have your own port-a-potty (much cleaner, obviously) within the confines of your home. Say you decide to update your basement and realize the macerating toilet would be better suited upstairs, only four screws need to be removed and the toilet can be reinstalled.
  • For those that are elderly or have special needs and have trouble traveling up or down the stairs, these easy-to-install and use toilets provide a great option for families who need it.
  • Worried about the time it’s going to take to get this thing in the ground? Don’t. The installation time is nothing compared to conventional toilets. The best part is that the installation requires essentially no breaking and digging.


  • Unfortunately, these toilets can get noisy at times because of their separate pumps and macerating systems.

When you compare the advantages and disadvantages of installing these toilets, the decision is pretty easy. Why go to all of the trouble of having to do a major plumbing overhaul and waiting for a toilet and the lines to be put into place when you save time and money by adding a macerating toilet to your home. Not only are you making your life easier, but the rest of your family and wallet will be thanking you later.


How to Install a Toilet Yourself!

These instructions are super easy to follow. But if feel like you need to hire a professional, then check out these posts on hiring contractors and handymen (and handywomen!):

Since you probably removed your own toilet yourself (if not, click here for detailed instructions on how to remove your toilet yourself), you probably have some of the same materials lying around. But here’s a listing of them:

Can you add a bathroom anywhere in your house?

The short answer is yes, you can install a bathroom almost anywhere that you can afford it. However, this will largely depend on your plumbing and electrical setup and what style of bathroom you want, which goes into another common question.

Frequently Asked Questions

Can the toilet be installed on a concrete floor?

You can install the toilet on a concrete floor. It may sound intimidating, but installing a new toilet can be a do-it-yourself project you can be proud of.

Is it difficult to install a bathroom in a basement?

Adding a bathroom to the basement is a large and difficult task. Complete the rough plumbing installation by connecting the basement to the existing floor and ceiling gutters and vents.

Do you need a special toilet in the basement?

Although a basement toilet is necessary to your basement bathroom, building a separate toilet in the basement is a different story. If this is the case, your plumbing will only work beneath gravity and not above ground. In most situations, you can connect to an existing underground sewer and be done with it!

Is it possible to install a bathroom without a rough finish in the basement?

Rough repairs are not common in older homes. If your basement lacks fundamental systems like gutters and vents, you’ll need to install them.

How can a shower be installed in a basement without causing damage to the concrete?

Looking at a toilet with a high-water level is the easiest approach to install a shower in a basement bathroom without damaging the floor. The Saniflo system is put on concrete floors, unlike standard basement showers, which require drilling the shower base and concrete to create a drain.

On a concrete floor, how do you fix a toilet?

This guarantee is as soon as the toilet flange is insertes into the drain hole. The pilot holes are then drill into the cement. Install cement screws to secure the flange to the cement board.

How much does it cost to put up a basement bathroom?

Adding a bathroom to a basement costs between $8,000 and $15,000 on average. You’ll save between $500 and $1,000 if you already have a drain, which is common in new homes and near the main drain.

The Cost to Add Another Bathroom

Many people don’t even consider adding a bathroom because they are sure bathroom remodeling is too expensive. Finding the space and building it out, along with adding plumbing, makes the cost to add a bathroom seem prohibitively expensive. It doesn’t have to be. The key is to find the right approach so the benefit of an extra bathroom outweighs the cost. Remember, adding a bathroom can significantly increase your home’s value, so with the right approach to bathroom remodeling, the ROI can be strongly in your favor.

How much does it actually cost to add a bathroom to your house? Not considering the cost you’ll recoup, the upfront investment can run anywhere from $3,000 if you already have a space in your home to install the bathroom to $25,000 if you have to add on to the footprint of your home.

You can easily spend more than this if you’re looking to install a large, luxurious bathroom, or you can save if you work with your existing layout and opt for simple fixtures, so make sure you get a quote that takes your project specifications into account.

Does adding a bathroom to a house increase taxes? The answer depends on a few factors. If your project requires a permit, then a tax assessor may notice the additional value you’re adding to your home. If you add on to the square footage of your house, you can definitely expect an increase in taxes. Even if you end up paying a little bit more in taxes, the added value to your home will far outweigh this small expense.

How to Install a Toilet: A Step-by-Step Guide

Note: We are not providing a detailed tutorial on how to remove an old toilet, but since some of you will need to do so, we are including quick and dirty instructions for how to do that below.

Phase 1: Remove the old toilet

You have to get rid of your old toilet first! To remove your old toilet, start by turning off the water using the shutoff valve–it’s usually located on the wall or floor very near the toilet. Flush the toilet to drain the water that’s in the bowl. Then use a plunger to force out any remaining water (it took us years to figure this little trick out, lol)!

Now you are ready to disconnect the supply line with an adjustable wrench. 

If your toilet tank is a separate piece from the bowl, separate the tank from the bowl by removing the tank bolts from the bottom of the tank with an adjustable wrench. The remove the tank by lifting it off the bowl. 

Finally, lift your toilet bolt caps located on the base and use a pair of pliers or an adjustable wrench to remove the bolts that are holding the base of the toilet in place. 

Now you are ready to remove the base of your toilet by pulling it straight up. Try to keep it completely upright to avoid any residual water spilling out of it as you move it. And have sponges or towels nearby just in case 🙂 

Phase 2: Install the new toilet

Step 1 – Stuff a rag into the hole in the floor to prevent sewer gases from coming into your home. Don’t forget to remove it right before you install the new toilet!  

Step 2 – Remove the old wax ring using a putty knife. It’s pretty gross, so I recommend wearing gloves.

Step 3 – Then take a good look at your flange (the piece that allows the toilet to connect to the floor). If it looks good and isn’t cracked, you are good to go. BUT, you will want to replace the old bolts with the new bolts that should come with your new toilet. 

Our flange was cracked. If yours is, too, no need to panic. You can use a flange repair ring. Just make sure you get one that is compatible with your existing floor flange. The easiest way to do that is snap a photo of your floor flange before heading out to buy supplies. If you can’t find what you need, show your photo to someone in the plumbing department and they should be able to help you.

This is what our floor flange looked like once the wax ring was removed.

In our case, we placed the flange repair ring (the

In our case, we placed the flange repair ring (the white ring shown in the photo below) into the existing flange and secured it in place.

Before you move on, be sure to position the new bo

Before you move on, be sure to position the new bolts that will hold your toilet in place. Below you can see our bolts positioned in our flange repair ring.

Step 4– Now it's time to install your n

Step 4– Now it’s time to install your new wax ring. Since our cement tile is quite thick, we used an extra thick wax ring. We rested the toilet bowl upside down on some soft foam mats and attached the wax ring to the bottom of the bowl. We prefer this (as opposed to positioning the wax ring on the floor before lowering the bowl onto it) because you can be sure the ring is in the perfect position before putting the toilet into place.

Step 5- The moment has arrived! You can now place

Step 5- The moment has arrived! You can now place your toilet bowl onto the flange. Be sure to align the bolt holes with the bolts in the flange. Once it’s in place, press down to set the seal. Just be careful not to move or tilt the toilet because you could break the wax seal, which would mean leaks. Not good.

Step 6- Place a washer and nut on each toilet bowl bolt and tighten them. Don’t over-tighten–you could crack the porcelain. 

Then use a hacksaw to trim off the excess bolt. Yo

Then use a hacksaw to trim off the excess bolt. You want to cut them short enough that the plastic bolt caps can snap into place.

Step 7- If your toilet isn't all one piece (most a

Step 7- If your toilet isn’t all one piece (most aren’t), you are ready to attach your tank to the toilet bowl. Every toilet is a little bit different, but you will probably need to install the “tank to bowl” gasket and insert the tank bolts and washers from inside the tank.

Align your tank bolts with the holes in on the toi

Align your tank bolts with the holes in on the toilet bowl and lower your tank into position. Then secure it by tightening the bolts.

Step 8- Last step!!!! You are ready to reattach your water supply line. After you do that, be sure to test the toilet for leaks by slowly turning on the water valve and filling the tank. Then flush your toilet and check where your tank and bowl meet, as well as where the toilet meets the floor, to see if any water leaks out. 

Step 9- Install your toilet seat. There are soooo many different ones, I’m not going to try to tell you how to install yours, but they are pretty easy to install and should come with their own instructions. 

Step 10- Your final step is to shim your toilet if it rocks at all and caulk it. If your toilet is firm and steady and doesn’t move at all, you are in GREAT shape. If it rocks a bit, use plastic toilet shims in the low spots until the rocking motion is resolved. Then use a utility knife to trim the shims flush with your toilet base.

Now let’s talk caulk! We always use DAP Kwik Seal Kitchen and Bath Adhesive Caulk in Clear. 

Just apply an even bead of caulk where you toilet
