Rustic sink built using a natural tree log

🪵 Materials and Initial Preparation

🌳 Select a suitable log.
Choose a thick, stable tree log with enough diameter to hold the sink. Make sure it is dry and free from structural cracks.
🔧 Remove the bark and clean the surface.
Use chisels, a scraper or a wire brush to clean the entire exterior of the log.
🕳️ Create a lateral opening for plumbing.
Cut an access hole wide enough to insert the drainpipe and water supply lines comfortably.

🪚 Hollowing Out the Log and Fitting the Sink

🛠️ Mark the sink outline and drill multiple holes.
Create a grid of perforations to simplify the hollowing process.
🔨 Carve the interior using hand tools.
Remove the wood gradually with chisels and special woodworking tools. This step requires patience and precision.
🧩 Test the sink fit repeatedly.
Insert the sink several times during the process to ensure a tight and stable fit.

🧴 Finishing and Protecting the Wood

🪄 Apply wax or protective varnish.
Treat the entire surface of the log to protect the wood from moisture. Natural wax enhances the texture and grain.
🚰 Complete the plumbing installation.
Once the sink fits perfectly, connect the drain and water pipes, ensuring no metal parts rub directly against the wood.

✨ Optional Upgrade: Add LED Backlighting

To elevate your project even further, you can install a small LED lighting system behind the log or at its base. This highlights the wood texture and creates a warm, cozy ambience, perfect for rustic or contemporary bathrooms. Browse more DIY ideas in the Vilssa DIY section.
