These are sleek-looking commode with the water tank attached to the seat, making it look pretty nice while covering a lot less space in your washroom. They are fashionable and commonly found in newly built houses or remodeled washrooms.
These are old classic traditional commodes that come in two pieces (tank and a bowl) and are then assembled into the final toilet. Still, the majority of US homeowners prefer two-piece toilets to one-piece toilets. You will have a toilet tank and a toilet bowl and have the option to mix and match the pieces together. These are very commonly found and also come cheaper than one-piece toilets.
Let us go in-depth comparing these key components to consider before making the decision.
- Size and weight:
One-piece toilets: You can always find a one-piece toilet as per your preferred size. They range from kid size to adult size and can stand, 10 inches to 16 inches tall. To go as per the comfort height guidelines they also come in a 17-inch size.
Usually, most one-piece toilets take up lesser space due to their sleek and compact design. The tank and bowl are attached which makes them occupy lesser space in general. Two-piece toilets can also be found in different sizes some of them also mandating comfort height guidelines. Both of them come in different shapes and sizes, to accommodate your bathroom’s layout and design.
Another important measurement while choosing a toilet is the rough-in, the distance from the center of the drainpipe to the wall behind the commode. Toilets are usually 12 inches high, but some have a 10- or 14-inch rough. Since the bowl size does not change, two-piece toilets provide more options for sitting on various sized roughs.
One-piece toilets are heavier than two-piece toilets because they have both tanks and the bowl, attached into a single mold thus making the commode heavier. This might also make the shipping and moving costs higher.
Although two-piece toilets also come in different shapes and sizes they are rarely as sleek and compact as a one-piece toilet.
- Build material and durability.
Both one-piece and two-piece toilets are built using Porcelain or Vitreous China. Those built from Vitreous China are comparatively stronger and slightly expensive. Most of the toilets sold in the US are made from Porcelain but customers can choose which material built commode they want to buy.
As the one-piece toilet is one single large piece, there are no joining parts needed to upkeep. Proven technically, the lesser parts or connectivity, the more reliable it will be. Hence, upkeeping a one-piece toilet is super easy. There is none or very little worry of water leaking out of the tank to mess up your home.
Two-piece toilets come as separate parts and thus need pipes and gauge to connect the bowl and tank. This can create a lot of ruckus with frequent leakage and rust. But as they come in different parts, they are easily replaceable. For example, if the tank starts creating problems in a one-piece toilet you have to replace the whole commode, on the other hand only replacing the worn-out part will do for two-piece toilets.
One-piece toilets are more durable but if two-piece toilets start wearing out, replacing single parts will be cheaper than replacing a one-piece toilet.
- Maintenance Frequency:
One-piece toilets are easier to maintain than two-piece toilets as they are inbuilt without any external rubbers or pipes to connect between tank and bowl. Unlike, a traditional two-piece there isn’t a joined part between mold and bowl and thus there are 0 chances of that uncleanable part being a breeding ground for germs and bacteria.
Also, there’s only a single commode to clean it reduces your time and effort while ensuring a very less amount of dirt and bacteria sticks into the tank.
Also, if a two-piece toilet isn’t regularly checked on there’s always chances of leakage from the joining pipes between the tank and the bowl. So, if you prefer a hassle-free and easier-to-maintain option, One-piece is always the better one.
- Flushing Power and Efficiency
The most common and simplest system used on regular toilets is the Gravity Flush System that uses the water weight to generate flushing pressure. Water siphoning action completes the flush. There are always options to customize as per your need with adding extra tit-bits like a Dual Flush or a more eco-friendly Waterless toilet.
If compared, there is no difference between the one–piece and two–piece toilets They can have the same flushing power and efficiency.
However, https://bargainbathroom.com/, a relevant blog about washrooms and home services claims that “American Standard Elongated Cadet Pressure Assisted Two Piece Toilet” is the best toilet seat in terms of flushing power but a “TOTO Ultramax Toilet – Siphon Flushing” a one-piece toilet is also more or less equally good.
Thus, Key difference in flushing power can be found as per the price in both (one-piece and two-piece) toilets, making higher-end models more efficient.
- Process and Cost to install :
The one-piece toilet is more challenging to install when compared to a two-piece due to its bigger size and weight.
To install both types of toilets, a wax ring needs to be placed over the waste pipe.
The commode is then twisted sharply to face front and placed on top of the ring at a slight angle. To equally distribute the weight, the installer sits on the toilet and leans front to back and side to side. The toilet is then bolted to the floor, with the bolts either hidden in the toilet skirt or covered with bolt caps. The water line is connected to the tank’s bottom and sealed. To search for leaks, the water is turned on and the toilet is allowed to fill before being flushed. This takes less than an hour.
Installing two-piece toilets is a lot easier as they come in separate pieces. But, without a proper plumbing skill set, you might face trouble while connecting the bowl and tank.
Installing both one-piece and two-piece toilets with professional help roughly costs around $100 -$200 so shouldn’t be a big dent on your wallet if you don’t want to get your hands dirty.
- Space required:
The shape of the bowl if elongated occupies a larger space and two-piece toilets occupy a bit more space of the wall.
National Kitchen & Bath Association recommends that a toilet should not be closer than 30 inches center to center to any other sanitary fixture. Also, Most of the US Zip codes require at least 15 inches (measured from the center of the toilet) from any side wall or obstruction. There also should be at least 24 inches of clear space in front of a toilet or bidet.
As common one-piece toilets come with bidets, for a small bathroom it is advisable to not have a bidet to meet standard criteria.
It is thus advisable for small bathrooms to have a square or a non-elongated bowl without a bidet, and as One-piece toilets have lower profiles they make good for smaller bathrooms with the benefit of having no bulky tank gasket to leak or occupy major space in the wall behind.
- Initial Cost:
One-piece toilets with their efficient design and the all-in-one-in-built system often come expensive. However, in recent years with an increasing number of homeowners preferring one-piece toilets the economies of scale have assisted in lowering down the costs.
To give you a rough estimate a one-piece toilet will ask you anything from $200- $2000, thus giving you a ton of choice for your essential commodity.
As two-piece toilets are common and have been in huge demand since forever, they are cheaper than one-piece toilets. An American Standard 288DA114.020 will come around $129 on amazon making it the cheapest on the platform and a “TOTO MW746305CUMGA” (a quite fancy one with dual flush) will roughly cost you $1500 on Amazon. However, for an average consumer and an average household options ranging from $130-$300 is advisable.
With installation, you can expect to shell out 300-500 for a two-piece toilet, and somewhere between $500-$900 for a mid-tier one-piece toilet. However, as one-piece toilets are more durable and need a lot lesser maintenance a customer can look at the long run while making the decision.
