Broadly there are three levels here, and they are very different in cost and complexity. A wet bar is a sink and a small fridge, good for a hangout. A kitchenette is a sink, a fridge, some counter, cabinets, and usually a microwave or a small cooktop, good for a guest suite or a light-use apartment. A full kitchen adds a real range or oven, a range hood vented outside, and full-size everything, which is what a long-term rental or true second living space needs.
Start with how the space gets used
Be honest about who is down there and how often they actually cook. A media room and game area with a spot to grab drinks and snacks does not need an oven. A wet bar or small kitchenette handles that beautifully and keeps the cost down. But if a family member is going to live down there, or you plan to rent it, people need to cook real meals, and that means a full kitchen. Building a kitchenette into a space that really needed a full kitchen is the kind of thing people regret a year later.
The guest-suite sweet spot
For a mother-in-law suite or a place for visiting family, a kitchenette usually hits the sweet spot. Sink, fridge, microwave, a couple feet of counter, and a small cooktop covers coffee, breakfast, and reheating without the cost and venting of a full range. Guests are comfortable and you did not overbuild.
The plumbing question decides a lot of the budget
Any sink needs water and drainage, and where your basement plumbing is already stubbed makes a big difference in cost. If we can put the kitchen area near the existing stub, or near the basement bathroom plumbing, the runs are short and the price stays reasonable. If you want it on the far side of the basement, we may be cutting concrete to run a new drain, which adds cost. We look at where your plumbing is before we suggest where the kitchen should go, not the other way around.
A full kitchen means venting and power
A real range brings two things a kitchenette usually skips. First, a range hood that vents outside, which means a duct run through the wall or ceiling to an exterior wall. Second, the electrical for a range, which is a heavier circuit than a microwave. Neither is a problem when we plan for it upfront, but both cost money, so they are part of the full-kitchen decision. This is also why a full kitchen is a bigger jump in price than people expect. It is not just more cabinets.
If you might rent it, the rules matter
Here is the part homeowners often miss. Whether a basement can legally be a separate rental unit depends on local requirements, and a full second kitchen is one of the features that can change how the unit is classified. Before you build a full kitchen with rental income in mind, it is worth confirming what your setup allows. We build basement apartments and ADUs across Tooele County and we can point you in the right direction, but the goal is to know the rules before we frame, not after. Building the wrong kind of kitchen for your rental plan is an expensive mistake to undo.
When in doubt, rough in for more
If you are not sure yet whether you will want a full kitchen someday, we can rough in the plumbing and a heavier electrical run now while the walls are open, then finish it as a kitchenette today. That leaves the door open to upgrade later without cutting concrete twice. It is a cheap insurance policy on a decision you do not have to make today.
If you are trying to figure out what belongs in your basement, tell us how you picture using it and we will tell you honestly which level makes sense and what each one costs. We do basement kitchenettes, full basement kitchens, and complete ADUs throughout Tooele, Stansbury Park, Grantsville, Erda, and Stockton. The consultation is free and it usually saves people money by steering them to the right build the first time.
