How to Refresh a Small Kitchen or Bathroom on a Budget

The Step-by-Step DIY Guide

The DIY Checklist:
What You’ll Need

A dingy bathroom or tired kitchen splashback can be easily revived without a full demolition. Replacing old, discoloured grout, renewing peeling silicone seals, and swapping out outdated hardware or damaged tiling immediately brightens up wet rooms. Having the right tools and sealant elements on hand prevents dampness from seeping behind fixtures in typical Irish bathrooms.

1.

SAFETY
GEAR
(PPE)

Protective Gloves (Heavy-Duty Nitrile or Latex): Essential for protecting skin from strong chemicals in degreasers, sanitising cleaners, and skin-drying tile adhesives.

Safety Glasses: Protects your eyes from flying fragments of hard, brittle old grout during removal or adhesive splashes.

2.

TOOLS &
EQUIPMENT

Grout Remover (Manual Rake or Hand Tool): Designed to scrape away deteriorated, stained grout between tile joints safely.

Squeegee or Grout Float: A flexible rubber-faced trowel used to compress fresh grout deep into gaps smoothly.

Notched Tile Trowel: Essential for combing and evening out adhesive bed ridges before setting replacement tiles.

Tile Cutter (Manual Hand Scribe or Lever Cutter): For scoring and snapping custom borders or edge replacement tiles cleanly.

Adjustable Wrench & Basin Spanner: Vital plumbing tools to reach tight spaces beneath basins or sinks to disconnect and swap out old taps.

Small Spirit Level: Ensures layout lines and new fixtures sit completely level.

Measuring Tape: For calculating spacing runs, replacement trim margins, and layout alignment.

Caulking Gun: Holds and smoothly feeds silicone sealant tubes along bath, sink, and worktop edges.

Bucket & Large Tiling Sponge: For mixing grout, washing away dried grout residue from tile faces, and general cleanup.

Utility Knife & Heavy-Duty Scraper: To slice through, lift, and strip away stubborn layers of old silicone sealant from bath joints.

3.

Materials, Fixings & Accessories

Sanitary Silicone Sealant (Mould-Resistant): High-quality waterproof sealant for kitchen splashbacks or sanitary zones.

Pre-Mixed Grout & Tile Adhesive: A convenient dual-purpose product perfect for fixing loose individual tiles and refilling joints.

Replacement Taps / Mixer Units (Optional): Fresh fixtures to immediately update old basins, sinks, or baths.

Plastic Tile Spacers: Ensures uniform joint widths (typically 2mm for walls or 3mm to 4mm for floors) when laying replacement tiles.

Concentrated Degreaser / Sugar Soap: For stripping grease, oil, grime, and soap scum off surfaces before painting, sealing, or tiling.

Plumber's PTFE Thread Tape: For wrapping around brass plumbing threads to ensure watertight, leak-free tap installs.

Microfibre Cloths: For removing residual tile dust and polishing tile faces clean.

Top Tip: Complete Deep Cleaning First.

Fresh silicone, grout, and adhesive will fail to bond on greasy surfaces. Scrub all tiles and corners thoroughly with sugar soap and a degreasing sponge. Allow the entire work zone to dry completely before opening your adhesives or tubes.

Top Tip: Fill the Bath Before Sealing!

When replacing silicone around a bath or shower tray, fill the tub with water before applying the sealant. Leave the water in place until the silicone is fully dry (roughly 24 hours). This pre-weights the tub, ensuring the dried seal won't snap or pull away from the wall tiles when someone stands in it later.

Step-by-Step DIY Installation Guide

STEP

01

Deep Clean & Prep Surface

Wash Down:

Mix your concentrated degreaser or sugar soap in a bucket of warm water. Use a scrubbing sponge to clean the entire target tile surface, removing grease, soap scum, and dirt. Wipe dry with microfibre cloths.

Remove Fixtures:

If replacing basin taps, turn off the water valves underneath the sink or at the main stopcock. Use your adjustable wrench and basin spanner to disconnect the copper tails, and remove old tap units. Clear away old plumber's putty from the holes.

STEP

02

Strip Old Grout and Peel Old Silicone

Scrape Silicone:

Carefully run your utility knife along the top and bottom of old silicone lines around baths or sinks. Use a scraper to peel out the old rubbery strands. Wipe down the exposed gap with white spirit or silicone remover paste to melt away greasy residue.

Rake out Grout:

Fit your safety glasses and gloves. Pull your manual grout rake along damaged, mouldy, or cracked tile joints. Scrape out roughly 2mm to 3mm of old grout depth, taking care not to chip the edges of the ceramic tiles. Vacuum the empty joint tracks free of fine grit.

STEP

03

Lay Replacement Tiles (If Required)

Bed Tiles:

If replacing loose or cracked tiles, scrape away dried mortar from the bare wall. Apply a layer of pre-mixed tile adhesive using your notched tile trowel to create ridges. Press the new tile firmly into the bed until it sits flush with the surrounding surface.

Set Spacers:

Push plastic tile spacers into the corners of the new tiles to hold perfectly uniform joints while the adhesive sets (usually 12 to 24 hours).

STEP

04

Refill Joints with Fresh Grout

Apply Grout:

Scoop a dollop of mixed grout onto your rubber grout float. Holding the float at a 45-degree angle, sweep it firmly across the tiles to press the grout paste deep into empty joints. Work in diagonal directions.

Sponge Clean:

Wait roughly 15 to 20 minutes for the grout to firm up slightly in the joints. Dip your tiling sponge in a bucket of clean water, squeeze it out thoroughly so it is only damp, and gently wipe diagonal circles over the tiles to clean the faces. Wipe again with a dry microfibre cloth once a chalky haze appears to polish the tiles.

STEP

05

Install New Taps & Brassware

Seal Plumbing Threads:

Wrap Plumber's PTFE thread tape around your tap thread tails 5 to 6 times in a clockwise direction.

Fit Taps:

Insert the new tap mixer stems through the sink basin holes. Slip on the rubber sealing gaskets and tighten the backnuts underneath using your basin spanner until secure. Reconnect water lines and slowly turn the water valves back on, checking for leaks around connections.

STEP

06

Run Fresh, Clean Silicone Joints

Prepare Joint:

Dry the wet-zone joints completely. Apply masking tape along the bath/worktop edge and the parallel wall tile edge, leaving a neat 5mm gap between them to guide your line.

Apply Bead:

Load your mould-resistant sanitary silicone into your caulking gun. Cut the plastic nozzle at a 45-degree angle to match your joint width. Pull a continuous, even bead of silicone along the joint.

Smooth and Finish:

Spray the wet bead with a light mist of soapy water, then smooth it flat using a specialized silicone profiling tool or a damp finger. Peel off the masking tape immediately after smoothing and let dry for 24 hours before wetting the area.
