The cost of renovating a bathroom with plumbing varies greatly depending on the scope and quality level. A simple update of plumbing components usually costs $3,000–$6,000, while a complete bathroom renovation with plumbing work can cost $8,000–$15,000 or more. The price is affected by factors such as pipe installations, choice of fixtures, underfloor heating, and the complexity of existing installations.
What affects the cost of plumbing work in bathroom renovations?
The scope of plumbing work is the largest cost factor in bathroom renovation. A simple update where you replace fixtures and toilet seats in existing locations costs significantly less than a complete rebuild of the plumbing system.
Plumbing installations have a significant impact on the price. If you move a shower, sink, or toilet, new water pipes and drain pipes will be required, which can increase costs by $2,000–$4,000. Existing installations from the 1970s or earlier often require extensive updates to meet today's safety requirements.
Underfloor heating is a popular upgrade that costs between SEK 8,000 and SEK 15,000 for an average bathroom. Installation requires the floor to be opened up, which affects both the plumbing work and other renovation work.
The choice of plumbing components plays a major role. Standard faucets and shower systems keep costs down, while exclusive thermostatic mixers and rain shower systems can double material costs.
How much do different plumbing components in a bathroom cost?
Installation of a toilet seat costs approximately SEK 3,490 including VAT without ROT deduction, or SEK 1,490 with ROT deduction. The price includes dismantling of the old toilet seat, delivery, and installation of the new one.
Bathroom faucets have an installation price of SEK 2,490 including VAT, or SEK 1,490 with the ROT tax deduction. This applies to both kitchens and bathrooms and includes dismantling, delivery, and connection to the water supply.
Shower systems vary greatly in price. A simple shower mixer costs SEK 3,000–8,000 including installation, while advanced thermostatic mixers with rain shower function can cost SEK 10,000–20,000.
Sinks and washbasins cost between SEK 5,000 and SEK 15,000 including installation, depending on the material and design. Wall-mounted sinks often require reinforcement of the wall, which can increase costs.
Bathtubs range from SEK 15,000 for simple models to SEK 40,000 or more for freestanding designer bathtubs. Installation often requires adaptation of the plumbing system and may involve extra work with drainage.
What unexpected costs can arise during bathroom plumbing renovations?
Water leaks and rot damage are often discovered when old installations are dismantled. Repairing water damage can cost between SEK 15,000 and SEK 50,000, depending on the extent of the damage and its impact on adjacent rooms.
Drainage problems are common in older properties. Replacing the main drain pipe can cost between SEK 20,000 and SEK 40,000 if excavation or access through other rooms is required. Old cast iron pipes often need to be replaced entirely.
Electrical installations often need to be updated when renovating a bathroom. Installing earth leakage circuit breakers, new sockets, and lighting can cost an additional $1,000–$2,500. Safety requirements are high in wet areas.
Walls and floors may need to be reinforced for new installations. Wall-mounted toilet seats require special construction, which can cost an additional $500–$1,000. Floor reinforcement for heavy bathtubs is another unforeseen expense.
To avoid surprises, you should always plan for an additional 15–20% on top of your original budget. A thorough inspection before the renovation begins will help you identify potential problems.
Is it worth hiring professional plumbers for bathroom renovations?
Professional plumbing installation is essential for safety and long-term functionality. Plumbing work in bathrooms requires approvals and must be carried out in accordance with applicable building standards. Incorrect installations can cause water damage that costs significantly more than professional installation.
Quality is crucial. Professional HVAC technicians have the right tools and knowledge to install systems that will last for decades. They are familiar with local building codes and can handle unforeseen problems that arise during installation.
The time savings are significant. While a DIY project can take weeks, professional technicians complete the plumbing installation in a matter of days. This reduces disruption to your home and the risk of errors that require rework.
Warranty issues are important to consider. Professional installations come with a workmanship warranty and insurance coverage. If problems arise, repairs are covered, which is not the case for DIY work.
Some simpler jobs, such as replacing shower hoses or taps, can be done yourself, but pipe installations, drainage work, and connections to the main system always require professional help. The safety risks associated with incorrect installations are too great to be ignored.

Frequently asked questions
Can I get a tax deduction for the entire bathroom renovation or just the plumbing work?
The ROT deduction only applies to labor costs, not materials. You get a 50% deduction on plumbing labor costs up to SEK 50,000 per person per year. Materials such as pipes, fittings, and bathtubs are not included in the deduction, but installation and assembly are.
How long does a complete plumbing renovation of a bathroom take?
A complete plumbing renovation typically takes 3-5 business days for professional technicians, depending on the scope. Simpler updates can be completed in 1-2 days, while complex renovations involving new piping can take up to a week. Always plan for extra time in case of unexpected problems.
Do I need a building permit for plumbing work when renovating a bathroom?
Building permits are not usually required for plumbing work in existing bathrooms, but notification to the building authority may be necessary for major renovations. However, all plumbing installations must be carried out by a qualified installer and inspected in accordance with local regulations.
What happens if rot damage or leaks are discovered during renovation?
Work must be halted in order to assess the extent of the damage. Rot damage must be repaired before plumbing work can continue, which may extend the project by 1-2 weeks. Costs vary from SEK 15,000 to SEK 50,000 depending on the extent of the damage and its impact on adjacent rooms.
Should I choose underfloor heating or a towel dryer to heat my bathroom?
Underfloor heating provides even heat and is energy efficient, but costs SEK 8,000-15,000 to install. Towel dryers are cheaper to install but less efficient at heating. Many people choose both options for optimal comfort and functionality.
How do I choose the right plumbing technician for my bathroom renovation?
Ensure that the technician is authorized by the Security Protection Agency and has insurance. Request references from previous projects and obtain written quotes that specify materials and labor costs. Always choose companies that offer warranties on both labor and installations.
Can I stay at home during the plumbing renovation of the bathroom?
It is possible but impractical because the water is often turned off during installation periods. Plan for alternative showering and toilet facilities. Many people choose to stay elsewhere during the most intensive days of work to avoid disruption and safety issues.
