Installing Your Own Mexican Sink




About: We moved to the Crowsnest Pass 10 years ago to start our own business. We now have two little boys (and a girl!) and a thriving coffee shop. We are both DIYers and enjoy renovating our home.

I've always loved the handpainted sinks we've seen while on holiday in Mexico. I swore that when I owned my own home, I'd have one in a bathroom to enjoy daily! Here I am with our sink Instructable.

We aren't complete newbies when it comes to renovating (we've laid a bit of flooring and done lots of painting, some drywall) but we aren't intimidated though, and if we want to try something, we think it through and go for it! This project, though, is not out of reach for someone with little experience. Why live day in and day out with a white porcelain sink if you could have a beauty like this for roughly $200-300 not including time spent.

Step 1: Find a Sink You Love.

We were north of Puerto Vallarta in Rincon de Guayabitos in November last year. I planned on finding a sink at a local market, but we were disappointed that much of the goods at the market were China imports. We came home from our holiday and bought this sink for $54 on a large auction website.

Step 2: Build or Buy a Vanity to Hold Your Sink.

We have a small bathroom and needed a specific size of vanity so the door would be able to open past it. My dad built us one to our specifications. If you are handy, you can do this. Other options would be to find an antique washstand or a dresser that you like. Most large hardware chains also sell vanities. Scour the thrift stores or hit up a few garage sales and you could find the perfect piece there too, for cheap!

Our vanity had a shelf underneath with an open back to allow for plumbing to enter. My dad delivered it primed and the photo shows it painted with the first coat of our chosen colour.

Step 3: Paint or Otherwise Prepare Your Vanity.

We gave this three coats of acrylic (water based) paint. Staining a wood piece would be nice too. We picked a blue to match a colour in our sink.

Step 4: Prepare Your Countertop.

We wanted a tiled countertop. We thought it would best set off the colours in the sink and add to the 'hacienda rustico' feel we wanted in our bathroom. Note: I don't speak Spanish.

Again, my dad made a simple plywood top. It had a backsplash and a small border around the edge. It would all be tiled. We made a template for the sink and cut the hole out. This took a bit of fine-tuning, as store-bought sinks come with a cardboard template. Mexican sinks don't. It took two or three cuts to get the shape of the overflow correct. We also cut holes for the faucet. Be certain that the lip of the sink won't overlap the holes you need for the faucet. Very important!

The trim around the edge was narrow, just wide enough for our 1" tile. The backsplash had to fit under some wood trim in our bathroom that was not coming out. If you are handy with a table saw, these customizable things are a better option than buying a vanity in a store, where you are stuck with just what they have.

The guy at the tile store will help you buy enough tile. We ordered 1 full square less than what he recommended and still ended up with a full piece leftover. We were taking into account the void left from the sink, but we didn't want to be left short either.

Step 5: Dry Fit Your Sink!

This is an important step. Be sure your sink fits with no rocking or weird movements and that your faucet fits as well.

Step 6: Cut and Dry Fit Your Tiles.

Just that. Cut and dry fit your tiles. We were using 1" tiles in a one foot square attached at the back by mesh. Some of them were cut in half or on the diagonal to go around the edge of the sink as well as around the quirky area by the overflow (in front). My dad cut these ones with a glass cutter and said they snapped easily. It's easy to shatter them, especially when working with such a small tile, so remember to always wear safety glasses!

We didn't want to look at the finished countertop and be able to easily see the one foot sections, so we cut the mesh in places and when gluing, slid them around just the slightest bit so that they looked 'handplaced'. We didn't want it to look like it rolled off an assembly line in a factory, but we also didn't want it to be sloppily made, somewhere in between.

One trick: we took a pic with our digital camera to reference where all the bits and pieces went. After each section is laid out, then you remove them to put glue down, it's tricky to remember just where this triangular piece and those three single tiles go back on. This worked pretty well.

Remove the tiles where your faucet will go. We also butted our tiles right up to the backsplash, then tiled up the backsplash.

We placed our tiles so that there was a smidge of an overhang, so that when we tiled the trim around the edge of the vanity, they'd be butted up as well and make for a neat edge.

Step 7: Start Slapping Down Some Glue.

We used a thin set mortar called Versabond. It has anti-mold properties (they probably all do). Mix it with water, don't inhale the dust and use rubber gloves. You will need a specific trowel with notches cut out depending on what size tile you choose. I think it's the smaller the tile, the smaller the notch (for example, 1/16th"), if you're laying 12" tiles on a floor, you'd probably need a deeper notch (more glue).

You had to work fairly quickly, as the open time (the time before it sets) was around 15 minutes. We did this in sections. Glue (thin set) on one quarter of the counter top, then with clean hands, place the tiles. Then more thin set and more tiles. Working quickly, we placed the tiles, then had just enough time left to work them around, wiggle them into place so that it wouldn't have that 'factory made' look. Again, we didn't want people to look at it and be able to clearly make out the foot sections of tile.

Following the directions on the label, leave to dry 24 hours.

Step 8: Time to Grout.

We were boring and went with a white grout. We thought it would look best with the light blue tiles and the white in the background of the sink. It's also in a bathroom, so we wanted a fresh, clean look. There are all kinds of colours of grout though, so don't be limited in your imagination!

Following the directions, we mixed up a bucket according to weight. (Weighing is a more accurate measure than by cups, ask any baker) Again, this stuff is kind of toxic, so use gloves and don't breath in any of the dust.

We mixed a bucket only to find that we didn't have enough. Mixing up more was really no problem. I was worried that the second batch might not match the first, but there's no difference at all.

You need a special grout squeegie (can't remember the name...trowel?) that has rubber on the bottom. It's flexible so that it can squish the grout in the cracks but it's not hard enough to scratch the tile. Always grout on the diagonal, so that you aren't inadvertently dragging grout out the cracks. Work the grout into all the nooks, up the backsplash and around the trim.

Step 9: Wipe Off the Grout.

Using a big, soft, wet sponge, wipe the excess grout from your countertop. Do this after you have finished grouting. Leaving this step too long (like overnight, don't do that!) will allow the grout to set up and it's like concrete. Work in circles and change your water often, making sure to rinse your sponge well. Your tiles might still look dull, but each swipe should get them looking more like the finished product! It's coming together!

This is really your last chance to leave this grout looking like how it will look on your vanity forever. If there are any goopy danglers, wipe them off now. Leave a nice, neat edge around the top of the backsplash and where your top meets the edge and trim. Tidy up the holes where the faucet and drain stopper will go through. Clean up the overflow divet and the hole where the sink will sit.

Again, follow the directions on the lable for the grout and leave to dry overnight. You want a gradual dry so that the grout doesn't crack and separate anywhere, so frequent misting with water in a squirt bottle allows it to ever-so-slowly dry out.

After it has dried completely (and no cracks, yay!) seal the grout with a...grout sealer. This is a clear, runny liquid that I used a thin paintbrush to apply. I imagine if you had a large surface to cover, you could probably just sponge it on and wipe off the excess, but I used a paintbrush to apply. That way, I knew I hadn't missed a corner.

Step 10: This Photo Isn't Really a Step...

We were just so thrilled to see it coming together at this point!

If you made it this far, you are ready to take this pretty sink to your bathroom and install it!

We first brought in the vanity, then the countertop. If you are halfway handy, or have a handy friend, this should all be within your grasp. Don't be intimidated! The sink is held into place by its own weight and by the plumbing alone. The drain plumbing (the elbow) comes in from behind (again, the vanity has no back) and hooking up the supply lines to the new faucet is fairly straightforward, especially if you were the one who unhooked the old sink.

We attached the countertop to the vanity using four small 'L' brackets from the hardware store. I'm sure there are numerous other configurations that would have worked too. The vanity is freestanding from the wall; the only way it's attached is by the plumbing.

Step 11: Place a Bead of Caulk.

We caulked around the edge of the sink to give it a neater look. It tidied up the places where we didn't cut and glue a smidge of a tile. We really like how it turned out, I don't think we'd have done it differently.

Not shown in this photo, but we placed a small piece of trim along the top of the backsplash. We didn't have enough space to tile it, but we did make a skinny trim that just wedged in there nice and neat. We painted it blue the same as the vanity.

    Thank you so much for posting these pictures. We are redoing our bath and using a quartz counter top. The fabricator is really puzzled about how to cut where there is NO lip at the overflow drain part and I am going to show them your pictures. Hopefully that helps them out.
    And nicely done!

    "You need a special grout squeegie (can't remember the name...trowel?) that has rubber on the bottom"

    This tool is called a float. Trowels are the metal tools used to mix and apply the mortar or glue.

    BTW, great job. I got one of those sinks with matching tile. My wife and I picked it up in Cuernavaca, Mexico about 8 years ago. I wish I still had the contact info for the store - they did (probably still do) a lot of mail order and shipping to decorators in the USA.

    A float, yes of course! I could never remember what the things were called!

    We are moving and have picked up a generic vanity to put in place of our Mexican one that's coming with us! No way are we leaving it behind. Three years later and it still looks fantastic. The new house has a lovely purple sink/toilet/tub that are hopefully on the way out!

    I sure would hope you found a home for those, especially if they were mid-century. I probably would have looked for a mexican sink that had some purple in it.

    The beauty is, anything will work for a vanity. Shop garage sales, flea markets or thrift stores for an old desk, dresser, etc. Anything like that will work and will look like a million bucks with a sanding and two coats of paint. :)

    Oh because I had thought you had said something that you were on vacation somewhere south. So I was just trying to figure out what region that was that they make such sinks. I am sure they make that style over here in the states.


    Reply 10 years ago on Introduction

    We had seen them twice before when travelling on the Caribbean side of Mexico (Cancun area and south) but the last time we went we were north of Puerto Vallarta (Pacific side) and we didn't see any pottery. It would have made for a more 'authentic' sink if we could say we brought it back from vacation, but there weren't any to be had.

    Wonderful work, well done I don't think I would have done it any better considering that I am a handyman and Mexican.
