Complete Bathroom Renovation: Steps, Cost and Tips

Want to know the step-by-step process, cost, and key tips for a complete bathroom renovation? This article has it all. A complete guide.

Deciding to renovate your entire bathroom in Mallorca is rarely a spur-of-the-moment decision. It usually stems from a series of small signs that gradually wear you down. Like the dampness that keeps creeping back in from the same corner, the dripping faucet even when you gently tighten it, or the shower feeling too short every morning. Finally, you look at your bathroom and think: okay, it's time.

And of course, before getting into construction, it's normal to want to know where to start, what steps to follow, and how much it might really cost, not the catalog figures. 

If you're looking for a clear guide, one that helps you navigate without getting lost, this post about a complete bathroom renovation will be very useful for you. 

Let's take it step by step and you'll see it very clearly.

How much does it cost to renovate a complete bathroom?

Calculating the cost of a complete bathroom renovation in Palma de Mallorca isn't as simple as just looking at an average price. Every bathroom has its quirks: some have walls that aren't perfectly straight, others conceal old pipes, and some don't even allow you to move fixtures without some serious acrobatics. 

Note that, at the very least, a 3 m² bathroom with basic materials is not the same as a slightly larger one with mid-range porcelain tiles or more elaborate furniture.

To be honest, the technical aspects are the biggest factor. Updating plumbing and electrical systems usually takes up a significant portion of the budget. Even so, having a clear reference point is incredibly helpful for getting your bearings and avoiding surprises when the actual estimates arrive. 

Let's get to the important details.

Current prices per square meter

Currently, most complete bathroom renovations fall within a fairly stable price range. Typically, the final cost is around [price range missing]. 600 and 1,000 euros per square meter, depending on the quality and the previous condition of the bathroom. 

For example, a 4 m² bathroom can cost between 2,400 and 4,000 euros if standard materials are used. 

Factors that make a renovation more expensive

This is where details that aren't immediately obvious but add up come into play. One of the most common is relocating the bathroom within an apartment, something that seems easy but requires modifying the drainage system and adjusting slopes. Incidentally, changes to the layout, lowering ceilings for recessed lighting, moving water connections, and reinforcing waterproofing also increase the cost. 

And then there are the materials: a simple tile is not the same as a large-format porcelain tile. 

Cost of replacing a bathtub with a shower

Replacing a bathtub with a shower is often one of the most rewarding home renovations, both for comfort and aesthetics. The price typically ranges from €900 to €1,800, depending on the type of shower enclosure, the quality of the shower tray, and whether any plumbing modifications are needed. 

Acrylic shower trays are more economical, but a resin shower tray offers safety, anti-slip properties, and a much more modern finish. 

Installation is relatively quick and does not require major construction work, although it is advisable to thoroughly check the condition of the waterproofing to avoid future leaks.

Step by step of a bathroom renovation

When you embark on a bathroom renovation, it's best to have a clear plan. Otherwise, everything gets mixed up and you start hearing the typical "this wasn't planned." The key is knowing that a complete, well-executed renovation almost always follows the same structure. 

And here's the story:

1. Demolition and removal of sanitary ware

This is where it all begins. The old furniture, fixtures, and wall coverings are removed. Okay, it's not the prettiest part, but it's what leaves the bathroom bare and allows us to see if there were any hidden problems. Now, in this phase, the walls and floors are inspected, and any irregularities are corrected if necessary. 

2. Plumbing and electrical renovation

This is where things really get serious. The old pipes are replaced, the water connections are moved to the correct locations, and the electrical wiring is installed so it won't cause problems for years to come. And, to be honest, this phase is the one that most determines how the bathroom will function later on. 

This is when you decide where you want the mirror light, which sockets you really need, or where each water outlet will go.

3. Waterproofing, welding and tiling

Many people here think it's "just" laying tiles, but as you can see, it's not. First, it's properly waterproofed to prevent leaks or problems after a few months. 

Next, the flooring is laid and tiling begins, which is when the bathroom starts to take shape. Choosing good materials helps a lot, but the professional's skill is what makes the difference: straight joints, clean cuts, and a solid finish. 

4. Installation of sanitary ware and final finishing touches

At this stage, everything starts to look like a bathroom again. The toilet, shower tray, vanity unit, and all the faucets are installed. And just when it seems almost finished, the final touches arrive: applying silicone sealant properly, fitting doors, checking for leaks, and those details that, if left undone, will cause headaches later. 

What permits do you need to renovate a bathroom?

This is one of those issues that always raises questions. Before you start removing tiles, it's normal to ask yourself what permit you need to avoid getting into trouble with the City Council or the homeowners' association. 

The good news is that, in most cases, a bathroom renovation is considered minor work, so the paperwork is usually quite simple. Even so, it's important to be clear about what can be done with a simple prior notification and what a proper minor works permit requires.

Generally, if you're going to replace wall coverings, a shower tray, bathroom fixtures, or even furniture, all you need is prior notification or a declaration of responsibility. It's a quick process: you submit a form, the estimate, and, if requested, a small sketch, pay the fee, and you can start almost immediately. 

However, if you are going to make more extensive modifications to the installations or change the interior layout, many local councils require a minor works permit, which does require a bit more documentation, but nothing dramatic.

By the way, if the renovation affects common elements of the building, such as downpipes or floor slabs, things change, because then you do need the approval of the community.

Recommended materials for modern bathrooms

Choosing materials for the modern bathroom design It's not just about aesthetics. Not just any old thing will do. Ultimately, what you're looking for is something that can withstand humidity, temperature changes, and daily wear and tear without losing that modern touch that's immediately noticeable upon entering.

To give you a quicker idea, here are some materials that work very well:

  • Microcement in bathrooms: It looks clean, seamless, and very modern. Plus, it's grout-free, which makes a big difference in maintenance. Ideal if you want a bathroom with a minimalist feel.
  • Large format porcelain: Perfect for a more elegant look. Durable, easy to clean, and available in countless finishes. Works great on walls and bathroom flooring.
  • Resin shower tray: Comfortable, non-slip, and warm to the touch. It represents a leap in quality compared to classic acrylics.
  • Water-resistant laminated furniture: They withstand humidity very well and require no special care. They work perfectly for bathrooms used daily.
  • Faucets in stainless steel or brass: It lasts longer, doesn't rust, and maintains its shine with little effort.
