First, you should customize Devise::RegistrationsController (you can add file app/controllers/registrations_controller.rb)

And see prepend_before_filter on devise registrations_controller.rb

prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ]
prepend_before_filter :authenticate_scope!, :only => [:edit, :update, :destroy]

Add show action to prepend_before_filter :authenticate_scope!

registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController
  prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ]
  prepend_before_filter :authenticate_scope!, :only => [:edit, :update, :destroy, :show]

  # GET /resource/sign_up
  def new
    super
  end

  # POST /resource
  def create
    super
  end

  # GET /resource/edit
  def edit
    super
  end

  def update
    super
  end

  # DELETE /resource
  def destroy
    super
  end

  def show
  end


  protected

  def after_sign_up_path_for(resource)
    after_sign_in_path_for(resource)
  end

end

Also copy the view of devise registration (edit and new template) to /app/views/registrations/ and You can make a file show.html.erb in /app/views/registrations/ folder for a profile page.

For routes of devise looks like :

devise_for :users, :skip => [:registrations]

devise_for :users, :controllers => {
  :registrations => "registrations"
}

authenticated :user do
  devise_scope :user do
    root to: "registrations#show", :as => "profile"
  end
end

unauthenticated do
  devise_scope :user do
    root to: "registrations#new", :as => "unauthenticated"
  end
end

Last, you to set a "path" in after_sign_in_path_for(resource) and after_sign_out_path_for(resource_or_scope) at file application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery

  private

   def after_sign_in_path_for(resource)
     # After you enter login info and click submit, I want you to be sent to the registrations#show page
     profile_path
   end
   def after_sign_out_path_for(resource_or_scope)
     new_user_session_path
   end
end

Note: I have tried this (to make sample apps), and it works. See log when sign in here, and log sign out here
