The Utility Room Renovation Checklist for Ireland: Every Decision, in the Order It Has to Be Locked

Last updated: 25 June 2026 · By Mossy Tariq, Founder — Property Blueprint Co.

A utility room renovation looks small enough to do without a plan, and that is exactly why so many of them go wrong. The room is dense with services and short on space, so the order in which decisions are made matters more than in almost any other room. A checklist for a utility room renovation is not a shopping list of taps and sinks. It is a sequence, and the value is the order.

Each item on this checklist has to be locked before the next trade can work, because the utility room gives no room to correct a decision made out of sequence. Choose the appliances after the units are built and they will not fit. Skip the tanking decision before first fix and you cannot add it later without starting again. The checklist below runs in the order the work actually happens, from the first measurement to the final payment.

A utility room renovation checklist is not a list of things to buy. It is a list of decisions in the order each one has to be locked.

This guide works through the utility room renovation checklist in five stages: planning, design, compliance, build, and completion, each with the specific decisions that have to be settled before the next stage begins.

What a utility room renovation checklist is actually for

The checklist exists to stop the utility room being built in the wrong order. In a large room, a decision made late is an inconvenience. In a utility room, where the washing machine, sink, tumble dryer, worktop, and storage all compete for a few square metres, a decision made late is a fixture that does not fit or a service in the wrong place.

A working checklist does two things. It sequences the decisions so each is locked before the trade who depends on it arrives, and it catches the wet-area requirements, tanking, drainage, ventilation, that the utility room shares with the bathroom but rarely gets credited for. Used properly, the checklist is the difference between a utility room that works for years and one that surfaces the failures catalogued in the utility room renovation mistakes guide months after completion.

The planning checklist: brief, budget, and measuring up

Before any design or trade, the planning stage sets the foundation everything else is built on. Work through these before moving on:

• Write the brief. Decide what the utility room has to do, whether it is wash-and-dry only or also drying, storage, a freezer, and a second sink, before anything is drawn.
• Set a trade-by-trade budget. Break the cost into plumbing, electrical, tanking, units, and finishes, so any drift is visible early, and remember renovation labour in Ireland generally carries the reduced 13.5 percent VAT rate.
• Measure the room accurately. Record the exact dimensions, the position of the existing water supply, drainage, and power, and the door and window openings.
• Locate the existing services. Mark where the water, waste, and power already are, because keeping fixtures near them is the single biggest saving in a utility room.
• Decide what stays and what moves. Confirm which services are staying put and which are relocating, knowing that moving drainage is the most expensive change.

The planning stage is where the budget is set against reality, which is exactly what the utility room renovation cost guide is built to support.

The design checklist: layout, appliances, and storage

The design stage turns the brief into a layout the trades can build. The appliances drive everything here, so they are chosen first, not last:

• Choose the appliances first. Select the washing machine and tumble dryer, and decide whether they sit side by side or stack, before the units are designed around them.
• Set the dryer type. Decide between a vented, condenser, or heat-pump tumble dryer, because a vented dryer needs an external duct that has to be planned in.
• Position the sink and worktop. Place the utility sink and fold or sort worktop where they work with the machines and the door swing.
• Plan the storage and the freezer. Allow for shelving or units for detergents, baskets, and cleaning gear, plus space for a chest or upright freezer if the room is to house one.
• Map the sockets. Plan enough sockets for the washer, dryer, freezer, and an iron at once, positioned clear of the water.

A utility room designed around the real appliances and the real tasks is a utility room that works. One designed before the machines are chosen is the most common way the room fails its owner.

The compliance checklist: registration, ventilation, and the wet area

The compliance stage is where the utility room is treated with the seriousness its services demand. In Ireland this is checked before the build, not after:

• Confirm the planning position. Internal works to an existing utility room are usually exempted development, but confirm this if the project alters the structure or extends the house.
• Engage a registered electrical contractor. Domestic electrical work must be carried out by a registered electrical contractor who issues a Certificate of Compliance on completion, which you can verify through Safe Electric.
• Plan the wet-area protection. Specify tanking and a floor drain, because although Ireland does not mandate a single waterproofing standard, the moisture and drainage provisions of the Building Regulations apply and tanking is best practice.
• Provide ventilation. Confirm an openable window or mechanical extraction in line with Part F, which every utility room needs to clear its own moisture.
• Check residual current device protection. Ensure the wet-area circuits have the required protection, which the registered electrical contractor will confirm.

The Competition and Consumer Protection Commission sets out your rights when engaging a contractor, and is worth reading before any agreement is signed.

The build checklist: first fix, tanking, and fit-out

The build stage is where the sequence becomes physical and irreversible. The order here is fixed, because each step seals in the one before it:

• Strip out and first fix. Remove the old fittings, then have the plumber and electrician set the water, waste, and power to the agreed positions.
• Install the floor drain. Confirm the floor drain is fitted and graded so water runs to it before anything is closed up.
• Tank the wet area. Apply the tanking membrane and have it checked before any tiling, because it cannot be verified once tiles are down.
• Tile and fit out. Lay the floor and any wall tiling over the membrane, then install the units, the sink, and the worktop.
• Connect and test the appliances. Have the machines connected and run a full cycle to confirm supply, drainage, and power.

This is the same wet-area sequence the bathroom waterproofing guide sets out, applied to a smaller room with the same consequences if it is rushed.

The completion checklist: what to check before final payment

Within The 12-Phase System, the final payment is the last leverage the homeowner holds, so it is released only against a checked and verified room. Before paying the final amount, work through the completion checklist:

1. Run a full appliance cycle. Confirm the washer fills, drains, and spins, and the tumble dryer runs and vents, with no leaks at any connection.
2. Check the floor drain and falls. Pour water on the floor and confirm it runs to the drain rather than pooling.
3. Inspect the wet-area finishes. Check grout, sealant around the sink and worktops, and tile for any gaps that would let water through.
4. Confirm the documentation. Collect the electrical Certificate of Compliance and any record of the tanking, because these matter at sale and insurance time.
5. Compile a defects list. Note every outstanding item and have it rectified before the final payment is released, while the leverage to compel it still exists.

A utility room signed off against this checklist is a utility room that has been verified, not just finished. The two are not the same, and the difference is the money still held when the last details are being chased.

Frequently asked questions

What should be on a utility room renovation checklist?

A complete utility room renovation checklist runs in five stages: planning (brief, budget, measuring, locating services), design (appliances first, dryer type, sink and worktop, storage and freezer, sockets), compliance (planning position, registered electrical contractor, tanking, ventilation), build (first fix, floor drain, tanking, fit-out, appliance connection), and completion (appliance test, floor falls, finishes, documentation, defects list). The order matters as much as the items.

What is the right order to renovate a utility room?

Plan and budget first, then design the layout around the chosen appliances, then confirm the planning position and registered trades, then build in sequence: strip out and first fix, install the floor drain, tank the wet area, tile and fit out, and connect the appliances. Finish with the completion checks before final payment. Each step seals in the one before it, so working out of order means undoing finished work to correct it.

Do I choose appliances before or after designing the utility room?

Before. The washing machine and tumble dryer, and whether they sit side by side or stack, drive the entire layout, the plumbing positions, and the sockets. Designing the units first and choosing the machines afterwards is the most common utility room mistake, because the appliances then may not fit the space or the configuration that was built for them.

Does a utility room renovation need planning permission in Ireland?

Internal works to an existing utility room are usually exempted development and do not require planning permission, but this should be confirmed if the project alters the structure of the house or forms part of an extension. The electrical work must still be carried out by a registered electrical contractor who issues a Certificate of Compliance, regardless of the planning position.

What should I check before paying the final invoice?

Run a full appliance cycle for leaks, pour water on the floor to confirm it drains to the floor drain, inspect grout and sealant around the sink and worktops, collect the electrical Certificate of Compliance and any record of the tanking, and compile a defects list of any outstanding items. Have the defects rectified before releasing the final payment, while the leverage to compel the work still exists.

Is a utility room really a wet area?

Yes. The washing machine discharges water under pump pressure, hoses can fail, and the sink can overflow, so the utility room carries the same wet-area risks as a bathroom in a smaller space. While Ireland does not mandate a single waterproofing standard for it, the moisture and drainage provisions of the Building Regulations apply, and tanking with a floor drain is best practice for exactly this reason.
