Important Considerations

When planning the construction of a bathroom, you must keep these factors in mind:

Concrete Construction

Plumbing rough in concrete construction is much more expensive than if the space is constructed with wood. Contractors have to break and restore concrete slabs to be able to install plumbing lines.

Hence, the labor becomes much more expensive and takes longer to complete. Contractors must take into consideration concrete specifications such as:

  • Plumbing depth
  • Plumbing type
  • Concrete slab’s thickness
  • Materials

Plumbing rough in preparation in concrete ranges from $500 to $2,000 on average. This price includes all materials and labor.

Type of Materials

The type of piping material that is chosen will affect costs. For most installations, contractors will use either copper pipes or PEX pipes. You may also have to consider the home’s existing plumbing system.

Old houses have plumbing components that are outdated and even illegal. Some materials have been banned due to safety and environmental guidelines. If you’re dealing with an old property, you may need to dig out old buried pipes and replace them with new ones.

 Copper Pipes

Cost of Copper Pipes

Copper pipes are preferred for most construction projects. It is the most commonly used material to rough in a bathroom. You can expect to pay about $2 to $5 per foot. A full repiping might cost you anywhere from $4,500 to $22,000.

Why copper you may ask? Because copper ( is one of the safest materials you can use. It has been proven to be safe over several decades. You do have to consider the winterization of copper pipes if you live in a cold climate.

Harsh winters with freezing temperatures may cause the pipes to burst. As long as you can winterize this material, you can be confident it will work great for your property.

PEX Pipes

Using PEX pipes for your basement bathroom’s rough in preparation is another great option. It will cost you approximately $2,200 to $5,500 on average. They are certainly less expensive than copper.

PEX is a strong material yet flexible. They can withstand a lot of pressure, so you don’t have to worry about pipes bursting or leaking. Another great advantage is the energy-efficient feature. This material retains heat and lowers your monthly utility bills.

However, the downside of PEX pipes is that they won’t last as long as copper. Since PEX is a type of plastic, it has a higher potential for damage. This material can be chewed by rodents inside your walls.

An alternative to PEX pipes is using CPVC material. The average cost is about $0.50 to $1 per foot. CPVC lasts longer, but the quality is debatable.
