We've done it with wardrobes - we used a company called Homestyle. We went to their showroom but actually most of it was kitchens (rather than wardrobes) but really liked it, quality was great. Ordered about a month ago, doors came a week or so later (custom sizes as we'd hacked the PAX system to make it look fitted) so they've only been in for about 3 weeks but really impressed so far. Customer service was great (they pointed out our measurements were wrong!!)
We considered that but the prices didn’t make sense. We just went with DIY kitchens - likely to be a bit cheaper overall and they do have tons of styles and colours + can paint the fronts and F&B colour you’d like.
Diet, I’d say so. If you’re getting a new kitchen that is. If you’ve got an existing kitchen and just want to change fronts, it makes sense to get replacement doors only.
However, with a new kitchen, whilst Ikea is very good value for money, DIY kitchens do higher quality carcasses and use excellent German drawer mechanisms etc. The prices start from not much more than Ikea but they offer the bespoke paints + can do bespoke sizing (they did a custom cooker hood for us). They also have a much wider range of cabinets. Ikea used to have a wider range but now they only go every 20cm for base cabinet widths. That can really limit your options. And last but not least, customer service is in a different league.
I've had kitchens from IKEA and DIY Kitchens - I'd agree with Jojo that the quality and choice is better at DIY. My IKEA kitchen was the old style Faktum so things might be different with the METOD range, and whilst it was very good, my DIY kitchen was better. Had it fitted by carpenter who normally worked for a German kitchen manufacturer and said quality was outstanding for the price. I now have one from Units Online (which is another online retailer). It was more expensive than the others (as it's wood) but definitely worth a look.
