How to install a sink and foot pump into existing cabinetry (great for RVs, campers, van conversions and outdoor events).

Let’s talk about sinks.

Accessing clean water from a faucet, and dumping dirty water down a drain, is a luxury. If you don’t agree, try washing your hands, brushing your teeth, or washing your dishes without a sink. Now do that repeatedly for a year. Let me tell you from experience that after a while, it’s a totally messy and inconvenient drag. I used to live in a camper with no running water. After a few months of brushing my teeth with old milk jugs filled with water, and spitting out the back door, I firmly understood the quiet dignity that comes with having a sink. 

This blog is for anyone who needs a portable sink that doesn’t require electricity. In it I will show you how I turned an old aquarium stand from craigslist into a self contained sink / adorable Aperol Spritz station for under $325. If you need plumbing for your camper, van, or skoolie – or you need a hand washing station for an outdoor wedding, this blog will show you how to put a sink into almost anything. Plus a few tips for putting upcycled cabinetry into recreational vehicles! 

Without further adieu, here’s how I turned a free aquarium stand from Craigslist, into an adorable little sink / Aperol spritz station.

Step 1: Gather materials

It took me a couple of tries to get it right. I’ve never used a foot pump before, so initially I bought the same fixtures, tubing, and faucet that I have used with electric water pumps. Rookie mistake! The water pressure from the foot pump wasn’t strong enough for the ½” ID tubing. After a couple of tweaks and a bit of googling I found a set-up that works pretty darn well. Here’s what I used: 

Cabinet + Tanks

  • 1. Aquarium Stand – $0!!!
  • 2. Reliance 7 gallon AquaTainer (x2 | one fresh water, one gray water) – $37.90
  • 3. 15” Undermount bar sink with drain and cover – $75.95
  • 4. Krylon Fusion Satin Peacock Spray Paint (x2) – $11.96
  • 5. Vinyl countertop sticker – $8.98
  • 6. 3/16″ shock cord (25 ft) – $16.99
  • 7. Black self tapping eye screws – $11.99

Plumbing + Fittings

  • A. 3/8″ orange tubing (10 ft) – $8.40
  • B. 3/4″ x 3/8″ Sch 40 PVC Reducer Bushing (x2) – $4.88
  • C. 3/8″ male thread x 3/8″ OD tube quick connect fitting (x2) – $4.49
  • D. 3/8″ Male In-Line quick connect – $13.48
  • E. 3/8″ Female In-Line quick connect – $14.28
  • F. Foot Pump with 3/8″ quick connect – $46.19
  • G. Reverse Osmosis Faucet with 3/8″ quick connect – $35.39
  • H. Camco Camp Drain – $18.10

Tools

  • Jigsaw
  • Drill

Step 2: Mark and cut holes (5 in total).

  1. Bottom: water tank hole. Water tanks are heavy, so I decided to cut a hole in the bottom of the cabinet for the tanks to rest on the ground. This is highly recommended if you are going to put a sink cabinet in your van or camper. I would also recommend having tie downs for your water tanks if you are planning to hit the road. 

2-3. Countertop: sink hole (jigsaw) + faucet hole (drill). The sink that I purchased came with a template but I ended up using the cutting board as my template. I wanted the cutting board cover to sit flush with the countertop. 

 

4. Shelf: drain and water line hole. First, I temporarily installed the sink so that I could mark where the drain was located. Next I uninstalled the the sink, removed the countertop, and cut a hole large enough for the drain and water lines.

5. Door: Mouse hole for the foot pump. I knew that I didn’t want to have to open the cabinet door to pump water. First I installed the foot pump and marked where it hit the door. Next I removed the door and cut an arch (this took a few times to get right :).


Step 3: Mark and pre-drill holes for eye screws + shock cord 


Step 4: Clean, Prep, and Paint

Step 5: Assemble cabinet (countertop, doors)

Step 6: Apply vinyl countertop sticker

Step 7: Install sink, faucet, and drain

Step 8: Install eye screws, thread shock cord, and tell a handsome dog that he’s a very good boy. Kiss his snoot and take his picture.

ft. Stanley: a very good boy.

Step 9: Install foot pump

Step 10: Cut tubing + Connect plumbing

Tip: you want your water lines to be as short as possible to increase water pressure. To connect lines to quick connect fittings, simply insert tubing and then pull back to lock. I chose in-line quick connects so that the fresh water tank can be easily removed from the cabinet for refilling.


Step 11. Pump your foot, wash your hands, and make yourself a cocktail! Cheers to a job well done! 


Tips for Van Life: 

Tip #1: Glue is your best friend! A lot of folks have asked me about installing IKEA or other existing cabinets (like the aforementioned aquarium stand) into their adventure rig. Ultimately, I don’t recommend it. These cabinets have a tendency to fall apart after a couple of dirt roads and changes in temperature/humidity. The vibrating screws shred the holes on washboard dirt roads and cabinets fly off walls. Not cool and not safe. If you can afford professional van cabinetry or you’ve got the chutzpah to make your own – I recommend that. That being said, if you want to dirtbag it with something cheap and easy, I totally get it (hence why I wrote this blog).

If you install prefabbed cabinetry into your van, do yourself a huge favor and use wood glue on every joint that is screwed together! Ask any professional van builder how they build and assemble their cabinetry, wall panels, and flooring. Glue is the holy grail in the van life builders toolbox. Where there are screws, there should be glue. Learn it, live it, love it. 

Tip #2: Dump your gray water in an appropriate place. Don’t be a bozo.

Tip #3: Don’t forget to winterize! Frozen water will damage your plumbing and tanks! Winterizing is easy in this simple system. All you need to do is dump your fresh water tank, then use the foot pump until your lines and the pump are clear of water, disconnect your quick connections, and finally dump your gray water tank. Easy peazy lemon squeezy.

A Guide to Aftermarket Windows

While working at Vanlife Customs, I was able to help hundreds of people navigate the process of converting a camper van. While there is no shortage of van conversion content available (we’ve all fallen down the youtube and Pinterest rabbit holes), it was my job to consolidate the vast sea of information into something useful and approachable. One of the very first steps of converting a camper van is installing aftermarket windows and vent fans, so let’s get started! 

We added 6 aftermarket windows to our Sprinter, totaling over $1,600.

Before

After

6 windows added:
– CRL Sliding door t-vent
– (x3) CRL 37″x16″ sliding windows
– (x2) CRL rear door windows

Before you decide to cut a bunch of holes in your brand new Sprinter, let’s discuss the pros and cons of adding windows and vent fans to your conversion.

Pros: 

Light. Most people purchase cargo vans without windows to convert. While these windowless metal boxes are great for stealth camping, they can feel pretty claustrophobic once the doors are closed. Natural light is one of the best ways to avoid the “free candy” vibe of a cargo van. 

Ventilation. Smelly gear, wet dogs, hot nights, and cooking up that fish that you just caught can quickly take over your tiny space if you don’t get some air moving. Tip: Whatever brand of vent fan you get, make sure you get a model that has both intake and exhaust functions as well as a rain sensor. It’s worth the extra $$, trust me on this one.

Visibility. I always recommend getting some sort of glass put in your sliding door. Being able to check blind spots while driving, especially if you aren’t used to driving large vehicles, is really important for safety and driving confidence.  Rear door windows were an awesome choice in our Sprinter build because we had a low convertible bed and I could actually see out the rear doors while driving. That being said, if you plan on having a loft bed with a garage/storage underneath, rear door windows won’t be very useful and they don’t offer any ventilation (they are also notorious for leaking). You might want to consider vented bunk windows instead. 

Cons:

Price. We added six aftermarket windows and a MaxxFan 7500k to Juicebox. While it looked pretty cool, and had some awesome airflow, it was definitely overkill and cost us over $1,600 with a wholesale account (#ouch). On average sliding door windows will run you between $350-$750, smaller bunk windows are $200-$350, and a MaxxFan 7500k should cost around $350 (although I’ve seen them cost upwards of $600 lately due to demand). If you aren’t comfortable cutting giant holes in your van, which is totally understandable, a reputable shop will charge you around $250/window and will typically fix any leaks that may occur in the future (be sure to confirm with them prior to making an appointment). 

Installation. If you don’t want to pay the pros, installing windows yourself can be intimidating, but it’s totally doable. There are dozens of great videos and blogs to walk you through the process. Two of my favorite tutorials are Live Like Pete and Project Vagrant. Try and catch any window/fan leaks (pressure washers at a car wash are a good test) prior to installing wall and ceiling panels. It’s not a huge deal to go back and add more sealant, it IS a huge deal to have to remove cabinets, walls, and ceilings because a leak caused your interior panels to mold, warp, and rot. 

Heat loss / climate control. Single pane auto glass is a major culprit for heat loss. Every window in your van reduces your insulation capacity and introduces the potential for cold drafts. So if you plan on camping anywhere that gets chilly, you might want to reconsider that all glass passenger van, or you can add some insulated window covers to your build. Take it from our friends Isabelle and Antoine over at Far Out Ride,

“Finally, adding insulated window covers are a must to keep the van comfortable; it makes a HUGE difference, we can’t emphasize on that enough!” – Far Out Ride

Privacy. If you are trying to be stealth in a city, light and noise coming from your windows is an obvious sign that your van is occupied. If you are at a camp site, festival, or parked anywhere around other people and you don’t want them to watch you change or sleep, it’s wise to consider a curtain solution like our signature Window Jackets that can remain on the windows at all times. 

3 leading aftermarket brands: AMA, CRL, and Motion

More things to consider: 

Window/Fan location. Primarily you’re going to want airflow for sleeping and cooking. That’s why you’ll notice most vent fans are installed above the bed or the kitchen. If you have a long wheelbase you can get away with having two fans and still have enough room for your solar panels. My standard recommendation is a fan above the bed, and a vented window behind the kitchen. Crack the window and flip the fan to exhaust mode while cooking, and then switch the fan back to intake for a cool breeze while sleeping.

Tip: if you have a kitchen that is located behind the driver’s seat, don’t install a t-vent window behind it. Most counters will be higher than the vented part of the window, making airflow difficult/nonexistent. Consider a smaller 1/2 slider (10”x33” is the most common). That way you can have ventilation, an insulated wall panel, and still have space to hang a spice rack!

Window Brands. There are several companies that make aftermarket windows for van conversions. Three big names in van glass are CR Laurence (CRL), Motion Windows, and AM Auto (AMA) windows . Having worked with all of these, I can’t say there is a clear winner. CRL and AMA have windows designed to fit seamlessly into your van’s factory window stamp, so if aesthetics are important – you might want to start there. Motion windows are slightly smaller (which means they can’t replace non-vented factory glass), but provide more airflow than the CRL t-vents. 

The most common piece of glass in a sliding door is a CRL t-vent window (that’s what we put in our Sprinter build). Aesthetically, it’s great, but the screened/vented portion of the window is relatively small and doesn’t offer a ton of airflow. It is also recommended that you close all t-vents and awning windows while driving. So if I had to do it over again, I would opt for the AMA half slider. The glass still fits into the factory window stamp, the vented area is larger, and the window can be open while driving.

Bunk windows are small windows typically in the rear near the bed. If you camp mostly in warm weather a cross breeze from two bunk windows and a fan can really make a world of difference, but drafty windows in cooler climates can be a real buzzkill. Also if you have a Promaster you will probably be sleeping in the van widthwise (6’1” and under sleep comfortably widthwise in a PM) which means your pillows and feet will block the window. CRL, AMA, and Motion all make bunk windows.

Tip: Pricing from all three brands fluctuates frequently with supply and demand, so buying windows during the winter months might end up saving you a couple hundred bucks. If at all possible, I would highly recommend buying your windows through a local rv/van shop and picking it up. Call around and see if any local shops have spare windows in stock. Most builders order extra windows because glass can be backordered for 2+ months. This also bypasses residential shipping fees, which can run you upwards of $200 depending on the window. Remember to check all of the glass for cracks and flaws before accepting the package.
